View 3 Replies View RelatedNetworking :: Network Setup - Router - Wireless Router Card ?
Apr 24, 2010I'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?

Networking :: Trying To Setup Ubuntu Box As Router
Apr 3, 2011I have multiple devices in my garage that need internet connectivity. I have my main Netgear router inside the house. I have a computer running Ubuntu in the garage with dual NICs.
Here's a map of how I have it setup now: [URL]
Here's my /etc/network/interfaces:
Code:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.1.60
netmask 255.255.255.0
gateway 192.168.1.1
auto eth1
iface eth1 inet static
address 192.168.1.5
network 192.168.1.0
netmask 255.255.255.0
broadcast 192.168.1.255
I was trying to keep everything on the same subnet. Eth0 is the external NIC, connected to the router in the house. eth1 is the internet NIC, which would go out to the devices in the garage. Now, I know it would be easiest to just connect a switch up and run all the devices in the garage off that switch. But the switch I have is a 10/100, and my network in the house is gigabit, and I want the PC in the garage to have gigabit access... which is why I'm doing this dual NIC setup and using the PC as a router, then the other devices in the garage will be 10/100.
In addition, I used the shell script as described in this article: [URL] to setup iptables. I also uncommented the net.ipv4.ip_forward=1 line in /etc/sysctl.conf. What am I doing wrong here? None of the devices in the garage that I connect up to the Ubuntu PC are getting connectivity. None are getting a DHCP lease from the main router in the house. The Ubuntu PC itself has internet access just fine though.

I do have 2 network cards, my router at the moment is starting to die and would love to have a more powerful router. I would also like to figure out how to do port forwarding in the router, as well as be able to see the load on the network cards. Maybe there is a program to show usage by user? As well as be able to do packet pritorization.

All outgoing traffic will route through DSL except for traffic destined for addresses on either eth0 or eth1 (web sites).

Jun 29, 2010I changed the passphrase in my Netgear WNR3500 router. I got the teenager's win7 netbook back online (wireless) no prob by simply changing the security key in windoze and it didn't effect my connectivity but when I attempt to enter my router setup by entering my local IP nothing happens, no response at all. I've rebooted twice and my connection is still very solid but I cannot access the router setup. The ONLY change I made was in the router's "passphrase".Not a big emergency at this point I suppose but I need to know what I need to change in Linux? Or to rephrase, in windoze7 passphrase=security key. In Linux?I can just reset the silly thing I guess but was kind of hoping I wouldn't have to and besides I anticipate the same trouble when setting the passphrase afterward.
View 1 Replies View RelatedDebian :: Setup Dnsmasq On A Network That Already Has A Router?
Feb 17, 2010I am trying to get more control of my small office network. It consists of several windows workstations, a debian box, and a ZyXEL P-660HW-D1 router, Right now, the only way to reach the debian box from other computers is to type in its ip address.
The goal is to be able to reach the box by just typing ://debianBox into my browser, though ideally I want to set it up to be something like ://debianBox.officenet, and to also reach other people's computers by typing ://mattBox.officenet and ://fredBox.officenet
The Zyxel router has a LAN page with a DHCP Setup tab with fields setup like so In the past I was able to mange this using an Orange router, but now I have to use the ZyXel.
So I installed dnsmasq on the debianBox, but I do not know how to configure it to get the results. I want and still get internet fromthe Zyxel router.
In the etc/hosts file of the debian box I added 192.168.69.15 debianBox, and for testing on my windows machine I set the primary dns entry of the Ip4 connection to 192.168.69.15 as well, but typing ://debianBox in my browser still gives me not found.

View 4 Replies View RelatedServer :: Setup Home - DSL - Netgear Router - DNS - Bind - For Use With Qmail On Cent-OS 5.3
Apr 30, 2010I would like to setup a qmail server for learning purposes (if you strongly feel Postfix is better, feel free to let me know). When I started setting up qmail (using Life with qmail), it suggested that having a DNS is the best approach. In the spirit of learning, I decided then to create another server for DNS only, and use that for qmail.
My problem is that, as this is a home installation, the internet is behind a Netgear DG834Gv5 router, on a DSL line that has a dynamic IP address. I am using DynDNS, but also don't mind having to update any DNS entries to keep up with the change, this is not exactly a production-grade setup.
In addition, I also have access to another DNS server where I can create authoritive entries for any domain I register. I have done that for a domain, and would like to point part of that to my home DNS so that I can learn.
So essentially, I would like to have a new zone for home.mydomain.org on my home DNS so that I can create new entries for *.home.mydomain.org such as qmail.home.mydomain.org etc. there.
I assume that this would include port forwarding on the router which is not a problem, but I truly have no clue where to start. I have a very basic install of Cent-OS 5.3 (no X and just Base a few admin and dev tools) and just installed the latest RPM of bind (9.3.x).

I set the modem back to PPPoE the problem was with the DNS server of the ISP so using ifup i set the dns t 8.8.8.8 (google) the connection is back , but when i set the modem back as a bridge slow internet does the router know that my dns is 8.8.8.8 or i should set the dns on the router ? I can't see an option to set the dns on the router ( i just enter my username and password from the isp to use PPPoE mode ) by the way i called the isp support they kept telling me to restart , i told them i did but i never restarted my pc . I'm sure if i tell them i'm running linux they will blame the os !
