Networking :: Multiple IPs To Wireless Router?
May 27, 2011
Current: Workstation --> Wireless Router --> Cablemodem --> InternetsIPs:192.168.2.1 --> 192.168.2.5>192.168.1.5 --> 192.168.1.1>{someIP} --> InternetsSo my first link has a Class C of 192.168.2.0. I want to add a different class C also to that firstink of 192.168.3.0. The reason is my LAN traffic will be on 192.168.2.0 and traffic will be on 192.168.3.0.The wireless router can be only set up for one LAN IP, which is 192.168.2.5. Is there some way to set up a vpn or nat or bridge or something else so I can run two class C's to the router and it will pass them along? Router is the Netgear WNDR3700.

My son lost his USB Wireless stick for his Computer. I had thought I heard that if you had a second wireless router, you could use it somehow to detect the wireless router you have already set up in your home (like using a wireless card)? Is this what Ad-Hoc is? Either way, can this be done and if so how? I use a WRT54Gx2 Lynksys router and have a TRENDNET TEW-432BRP wireless router and also a spare D-link DI-514. I use ubuntu 10.04, and also wanted to know if I connected one of the router to his on the LAn port could he connect msaybe through an Ad-Hoc on my local computer here? He uses XP on his. I'm a newbie to linux and networking in general.

I moved my server and network equipment, and now the wireless works but I cannot get my server online. I host a website, so this is kind of urgent.
I have a wireless router and can access the internet fine on my laptop. My server is wired & connected to the router. It sets up the networking properly.. ifconfig has an ip address, the default gateway is present. But I cannot ping google, or even the router. It says destination host unreachable.
So I go back to the laptop to check the router settings.. sometimes it likes to assign the server the wrong internal ip. But, I can't access the router settings either! The page (192.168.1.1) times out. Same with trying to ping the router. How can the laptop be online if it can't reach the router?
Oddly, ifconfig on my laptop reports an ip address starting with 99.233. It's always given me an internal address starting with 192.168. What's going on here? Is the router not allocating an internal ip? I use wicd to connect, if it's relevant.
We have a windows laptop that can only get a "local connection". Now it does sound like the router is forwarding directly to my laptop, instead of allocating internal ips.

I want to set up a Linux box as a wireless router to replace our existing Netgear WNR1000 router, as I believe the Netgear does not support the coming IPv6 protocol. Unfortunately, it is not flashable with OpenWRT or DD-WRT presently.
As we have Comcast, our cable modem acts as a dumb modem according to the customer support guy I talked to, and our router is the one that asks for the IP address from DHCP. Thus, when Comcast switches over to IPv6, I don't believe my existing router would work, correct?
My idea is to take a Linux box and put two NICs and a wireless adapter in it, using IPCop or Smoothwall to set up a router. I could then enable IPv6 support for when we have IPv6 with Comcast. Is that possible? Would there be a way to get BIND to hand out private IP addresses in the same subnet on the both the LAN NIC and the wireless card?

I'm having trouble getting my network set up the way that I want it/had it. You see, when I first set up my network, I just had my cable modem going directly to my standard wired router (A D-Link DI-604), which had DHCP,and was connected to all of the computers on my network. I had one switch hooked up to one of the ports of the router, but this was a regular switch, and it would not try to assign IP addresses, it would just pass through the DHCP info as I wanted.
Now however, my network setup has changed. My room mate and I both got laptops, and we decided that we wanted to have wireless access so we didn't have to constantly plug in to the router.
Now my network is set up like this: The modem is hooked up to the router(DI-604), which is hooked up on the LAN side to our computers, our switch (which is hooked up to 3 more computers), and to a wireless router card (A Gigabyte GN-BC01).
The wireless router card has two jacks for ethernet. One for WAN, and one for LAN. The LAN side we have plugged only into the computer in which the card is installed.
Now the problem is this: The wireless router card comes with DHCP by default, and it's assigning addresses to the laptops and to the computer hat it's in, and worse, the IP addresses are on a different subnet than that of the main dlink router. The Main (dlink) router assigns addresses from 192.168.0.1 (itself) to 192.168.0.254, while the wireless router card assigns addresses from 192.168.1.1 to 192.168.1.254 (itself).
Because of this, I cannot access services on the wireless network from my wired network or vice versa. The first thing I tried was setting the card to assign addresses from 192.168.0.12 to 192.168.0.253, however it just said "internal error" when I tried to do this. I decided that this may be because it sees that it was being assigned an address on it's WAN side on the same subnet. So the next thing I tried was disabling DHCP and setting the "LAN IP Address" to 192.168.0.12, hoping that the DHCP would just go through the card, like a switch. I would have set the LAN IP address to be assigned by DHCP, but this was not an option, so I decided that'd be the best thing to set it to.
Once again however, setting the LAN ip address to an address on the same subnet as that of the IP assigned to it's WAN side caused it to report an "internal error". I verified that this was the issue by setting the LAN address to several other private IP addresses to test (I.E. 10.0.0.1, 192.168.3.1, 192.168.5.12).
My question then really is: How do I set up both routers so that I can access services and computers from each network from the other network. Should I set them with different subnets and set the gateway on the wireless network to the main router? To the wireless router card? Should I put them on the same subnet? Will it know how to communicate?

I have 5 linux ssh servers at my office that are behind a router. How do I connect to any one specific server from outside the LAN? Do I have to port forward the router giving each machine it's own port? That seems clunky.

I have been working with Linux for about 10 years and I have a good understanding of IPv4 networking and routing but not so much detailed knowledge of implementation or specific networking packages.
I have a Linux system running a custom-built (Linux from Scratch) distribution and using 2.6.15 kernel. My system has 4 Ethernet controllers (eth0, eth1, eth2, and eth3). I have intentionally left out support for forwarding/routing of packets as this machine is not intended to be a router and I specifically do not want it to be able to so. My intent for the machine is to function as a server to 4 different and separate networks without allowing traffic or hosts on one LAN to access or adversely affect those on the other LANs.
My main question: is there a way to completely isolate the connections to these LANs and if so, how might I achieve it, and through what packages?
I have been having some issues:
1) Default gateway. With only a single default gateway, network requests from a LAN that is not directly connected to one of the 4 NICs and for which there may not be a static route defined, may send a response to the default gateway which is on one of the LANs connected to a different NIC than the one that I received the initial request on. Is there anyway to isolate outgoing messages to only go out on the NIC that the corresponding request was received through?
2) Default gateways. I have a requirement to allow DHCP on these interfaces. It is possible that the DCHP servers on each of the 4 LANs may provide a default gateway, but I don't see how I can make use of that. I know that there is a way to configure multiple default gateways via the iproute2 package (which is what I am using) but I don't know how to make sure that the correct default gateway is used for requests that were received on a specific interface.

wlan0 Authentication capabilities :
WPA
WPA2
CIPHER-TKIP
CIPHER-CCMP
Those are my authentication capabilities, obviously. I am using a WEP encryption for my wireless router and according to this, it will not allow me to connect. Is there anyway to allow that? The wireless card works just fine in Windows, even on the same network encryption type. Using a Intel Wireless/Pro 4965 ag. Note* this is my mother's router and whatnot. She won't change it the encryption type.

I installed a Tenda W322P wireless card in my dual-boot PC running both Windows XP and Ubuntu 11.04. The card worked straight out of the box on XP, but does not function correctly under Ubuntu. My apologies for any missing/irrelevant information, I am having to post this from the Windows boot so the Ubuntu settings are not directly available at the same time as internet access.I followed the process detailed here htURL...to install and configure the driver (I believe from reading other sites that this card is the Ralink RT3062 chipset), blacklisted the original RT2860 driver that was in use (couldn't even get the card to scan for wireless networks with the default driver) and restarted the interface.
Since then, sudo iwlist scan can find my wireless router but when I attempt to connect to it, it seems to enter a loop of requesting the WEP key then pausing for a while before re-requesting the key. I know I have the key value correct because it is copied and pasted from the same text file I used to copy and paste into the passkey field on the Windows boot. Attempting to connect to the router using Ubuntu also has the rather unfortunate side-effect of crashing the wireless router, killing off all other device connections until the router has been reset.

a wireless router (box) is went stuck, I found that when it is stuck it uses strange IP local address remote address 10.112.112.112, today is also went stuck but this time the gateway was 10.112.112.112. I had to switch off, switch on teh router to function properly. I am using DSL connection normally the gateway is likie that 78.8.... and my IP (dynamic) like 78.8.240..... Is there any default meaning of 10.112.112.112 in teh net connections?

I'm trying to set up a wired/wireless linux router. it wirelessly connects to a network, then is wired to the internet port on my netgear wgr614.
eth0 (wireless) is dhcp
eth1 (wired)
The router
Internet port is static
And local network
I turned forwarding on, set the iptables for masquerade and nat, but i'm not really sure what i'm doing wrong. any pc connected to the wrg614 can see the pc thats supposed to be forwarding packets but can't see any further(the other router at 192.168.1.1 or the internet).

I am currently running Fedora 10.92 on my desktop and have a linksys network card, one of the ones that uses the b43 wireless driver. Fedora sees the network card, wlan0, and driver but I can't get it to see the router and connect. I have tried to manually put in the ip,ssid, ect but to no avail. I tired starting network manager from terminal which worked for me in fedora 8 and ifconfig wlan0 up but nothing seems to work.

When fedora initially starts up, the network manager shows all the available wireless connections available to me. However, when I select my wireless connection, it will go through the loading process where it shows the two green dots and the circular moving blue streak, then it prompts me to put in the wpa password.
This is where the trouble starts...when i input my wpa password, it will proceed to attempt to connect to my network but it never succeeds in doing so--it will keep on asking me to input my wpa password. when i finally get sick of doing it over and over again, i just hit cancel instead of retrying to connect.
After i stop trying to connect, the network manager no longer shows all the available wireless networks--the list is completely empty, and i can find no way to get the list to show up again, with the exception of restarting my computer.
I am able to connect to the internet with a wired ethernet, but id like my wireless to work.

Can I use Mint as a Router service, similar to the service in Ubuntu (called: Router Advertisement Daemon?). Does Mint support this and what solutions are available for this?
Have dabbled in Linux very briefly, but almost no experience on how to install or find programs, so please explain in detail!
EDIT: I'm looking for something easy and simple, like what Virtual Router or Connectify does for Windows 7...

last night as a download was going the Internet just stopped connection. Then asked me for the WPA & WPA2 personal password. I didn't know what to put since I had already tried multiple pass words I restarted the router.Now for some reason the computer won't pick up the router wireless signal. It picks up multiple connection's around my area so I know that it's not the wireless card. The router is connected via ethernet at the moment so I know the internet works.Do I have to find the ssid? Maybe the router reconfigured it's self when I restart it and broadcasting mode turned off... I just don't know

I have a wireless router HG520s. I have enabled a hidden (nonbroadcast) mode on channel 1 with WEP encryption (64bit / 10 hexadecimal chars). Mac filter is not enabled. Name of ESSID is "homenet", everythig else is usually by default.Now, when I try to connect with my laptop (os=winxp) I can't see the essid (because it's hidden)Well I know I have to set it manually. I open windows wlan manager and go advanced (win-firewall is disabled) and create new wlan network profile to connect with, I set up the credentials, name of ap, enc wep, and the rest of stuff (I assume you know how 'hard' it is) and then I can see when refresh wireless network my own network, but the PROBLEM is that I have a Limited Access or/and no access to internet.
I remind you that router is well connected and there is internet on lan ports, but I can't access through wireless with my laptop.In fact I can only see my essid and that broadcasting is active, pwr is good, distance is not the problem. My laptop cannot get ip assigned and the same problem is with my E51 nokia (No Gateway Reply!).I think I said enough. Now any of you guys please try to explain me how's this possibleThe problem is same with ubuntu. My wife is using Win7, I'm on Ubuntu and my son he's on laptop with XP installed

I have a computer running Ubuntu, and a MacBook Pro. I need to buy a decently cheap wireless router that I can hook up to my Ubuntu so that it will send wifi signals and I can use the wifi to go online with my MacBook Pro. I was about to get one today, but remembered how Ubuntu is picky about working with things like that. I'm only going to be using it to get signals around the house which isn't that big at all.
So what would be the cheapest and decently efficient wireless routers that I can use which Ubuntu will cooperate with?

I am having problems connecting to my new router. It just does not appear in the list of connections under Network Manager. It is not a problem with my laptop's wireless adapter as I can connect to another wireless router. It is also not a problem with the router itself - my Nintendo Wii can pick it up over Wi-Fi and use it and that is further away from the router. It also works if I ethernet it straight into the laptop.The router was provided by Sky Broadband and is a D-Link, pretty standard type of ADSL router with four ethernet ports, wireless and telephone cable socket. I am using the default settings for the SSID and network key, as well as the encryption type (WPA).Ubuntu version = 10.04. The wireless adapter is a very standard issue onboard Intel device but as I say, I can connect to my old Belkin wireless router no problem.

I'm running ubuntu v. 9.10, kernel 2.6.31-22-generic, and it's currently connected to the internet via one of those mobile 3G USB keys (HUAWEI E1550).
The problem is that I tend to run multiple computers concurrently and it would be beneficial if I could have internet access on the lot.
So I was wondering if there's a way that I could use my netbook as a wireless router in order to host a wlan.

I have installed ubuntu 10.10 and am really happy. I want to sort the wireless conection out now. I have been through this forum for hours today and can't get it working. I have a Broadcom wireless card, which seems to be working fine, but I am not 100% convinced.I have attached the output of some of the commands that I have seen referred to on here.
I am using the wired connection on the same router, so the router connects fine.I click on the network icon and I see the skyNNNN router in the list. I have tried connecting to it and it asks me for my password, which I provide then nothing happens until it asks me again.I have removed the security from the router and I then see the same skyNNNN router without a
lock icon. I try to connect and it still fails.I am not using an access list on the router, so there is no issue with the mac address.

i wanted to know if i can use my laptop as a wifi router; with encryption password and all security so if another computer is in the range can detect the signal and then try to connect to it with the encrypt pass.
also i have one more doubt. can a wireless router be used as a wifi ethernet card and detect wifi signals nearby and connect to internet. suppose i have a wireless router and i connect it to my desktop(with lan cables) which has ubuntu installed, and theres a wifi connections nearby can i connect the desktop to the internet.

i did googled for that for a while now, but didn't found anything relevant so far, or did i missed something? i need to share a pppoe connection, using an infrastructure wifi network, how can i do that in ubuntu?
forgot to mention, ad-hoc just won't do it for me, the other devices, either dosen't support it, either get a password error. also, i would need some help for establishing the pppoe, i previously did that on another machine, but that was long ago, and it was a big head ache, it would only dial on startup, and no redial or disconnect posibilities whatsoever.

I'm trying to connect to a new Belkin wireless router, but wicd refuses to connect. I've been reading some of the other threads but they haven't made much sense as the hardware is different.
The output from the iwconfig command is as follows:
When I ran lspci it told me I had a RaLink RT2800 802.11n PCI Network Controller. On the box it says it "Supports the most popular systems" and mentions Linux. I'm using a 63 character WPA2 password, which has been copied from a USB key, so I know that is correct.
