Networking :: Setting Up Linux Box As IPv6 Router To Replace Netgear WNR1000 Wireless Router?
Jun 18, 2011
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 have been struggling to get FC15 to act as an IPv6 router for a while now, am sure I am missing something trivial.. The idea is that I have a ppp / adsl connection (this works fine), use the wireless card on my pc with hostapd and dhcpd to provide connections to other pcs (works fine), and radvd to delegate ipv6 addresses.
The issue seem to be that as soon as I turn on ipv6 forwarding (net.ipv6.conf.all.forwarding =1), the ppp connection no longer gets an IPv6 address. This means the router cannot ping any ipv6 address outside my network.
If I disable ipv6 routing, my router gets an IPv6 address on its ppp connection, and can ping things such as ipv6.google.com just fine, however (of course) no packets are forwarded from my network and radvd complains that forwarding is disabled.

I decided to try and get my network ready for IPv6. All of my hosts are set up to do stateful autoconfig, I have radvd installed and working, and I can ping6 ipv6.google.com from my Ubuntu server. However, when one of the clients on the inside tries to ping6, no packets return and I get this message in the router's syslog:
Code:
Feb 8 17:55:17 foo kernel: [ 1344.824474] Dead loop on virtual device tun6to4, fix it urgently!

I have a client that has a basic network that uses comcast cable. He bought a NETGEAR N300 wireless router which has a 192,.168.3.X network and he attempted to add it to his 10.10.10.X network and all is fine. He laptops and such can get to the internet fine. The issue is he cannot get to any of his devices on his 10.X network. I have looked at his comcast router which is controlling his 10.X network to see if I can add addition routing to his 192.X network. but didnt see anything. I also am not to familiar with the N300 wireless router. I was going to have the wireless DHCP turned off and some get it to pull the DHCP stuff from the comcast side but dont see any area to do this.

i must make this work with the use of virtual pc's. I have vm player and installed fedora ( the latest version ) and one xp . So i have 2 virtual pc's. I'm making it simple for start so i can add more pc's when i see that it is working. I have setup a dhcp server at the fedora virtual pc. The fedora virtual pc is like a soho router. The xp pc is getting ip from dhcp while the fedora one has a static one.
My pc is behind an adsl router. Both virtual pc's can see each other which means i have no connectivity issues.Im trying to setup a squid proxy ( transparent one ) so for example the xp pc can access porn sites and such. I used all required configuration for the squid to work and started the service. Ive also inserted with iptables the commands to forward all incoming port 80 packets to port 3128 ( the squid ). It doesnt seems to be working and i thik i know why but i dont know how to fix it.
Because the xp has a gateway at 192.168.1.1 ( the adsl router ) packets go directly to it and not to the soho router ( fedora virtual pc as i intend to do) What can i do to solve this problem ? How can i forward all packets to go to the fedora virtual pc first and then the fedora pc to forward them (if necessary) to the adsl router? PS. I used Bridged connection on the networking configutration on the vmware player ! If you also want i can post the code for squid or iptables if needed !

I have internet access through 3G/4G USB dongle direct into my Ubuntu 10.04 box. Works great! Now I would like to share this connection out through my Netgear WGR614 wireless (and wired) router. Any clues? I've tried the simple (GUI) instructions using Network Manager, but just can't seem to get it right. Previously, I had DSL and this plugged nicely into the WGR614 and internet and ethernet access was had by all. Now, I'm a bit confused on how to get the sharing (ethernet and wireless) between my Ubuntu box and the wired/wireless network while at the same time getting Internet access to all through the Ubuntu box.

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?

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 cannot connect to internet. I just installed Fedora 12 w/ the Live CD and I have a Linksys WMP54G Wireless Card (v4.1 I believe) and it apparently installed fine upon install of fedora. It will not thought connect to the internet. It reads my connect (NETGEAR-2.4-G), my router is a Netgear WNDR3300. It worked perfectly fine on Windows XP. Like I said, it picks up my wireless connection. But when I go to connect it attempts to connect for like a minute or two then goes back to not connected.

My router doesn't support IPv6. I'm wondering could IPv6 support be provided by just upgrading the firmware? I thought it was just a protocol. Also how does not having IPv6 support affect home users?

I have just installed Kubuntu 9.4 and my wifi will not work. dmesg tell me it is looking for IPv6 and my router does not support it.
how I can tell the OS to ignore IPv6 and use IPv4?
I have read writing alias net-pf-10 off; and alias ipv6 off in /etc/modprobe.d/alias is supposed to work but Kubuntu 9.4 does not have an alias file in modprobe.d

I have a Netgear DG834 ADSL router (v3) which I have used for a couple of years. Prior to that I had a v2 of the same router, but upgraded for the one that supports ADSL 2+ (here in the UK).
Recently I have been having problems with the connection often being dropped, and when I access 192.168.0.1 for the router admin page, when it is not working I get no IP address listed for that of the ISP's server, and sometimes as well the upstream and downstream speeds are listed as 0 kbps.
Usually this was resolved by rebooting the router.
However, for the last couple of days, when using Ubuntu 9.04, the page of the router at 192.168.0.1 will not load. I have tried numerous different browsers, and none of them will give the router admin page.
When I tried booting from a live CD of Fedora 13, the router admin page came up just fine, no problems (although still not getting a proper connection to the Internet).
I was going to try to use the older router I had, but so far, as I cannot access the router admin page in Ubuntu, I have not done so (not had the time, and now I am at work posting this).
So there must be a problem in Ubuntu that is preventing it showing the router's admin page. The Network connection details show that the router has given the PC an IP address of 192.168.0.6 and the DNS servers are listed, so I know that Ubuntu is talking to the router, but it is not allowing me to access its settings in any way.

For my broadband Internet I have several computers connected by cable to a Netgear DG834Gv5 router which has its own firewall.I have the wireless turned off by choice.My desktop and laptop are Linux only. (Ubuntu lucid lynx) I use the same username and password (very strong password) on both.What I want to know is can I set things up so I can browse and copy files between the computers using say nautilus on either computer?if not nautilus then I would happy to be able to do the same via a terminal window.I am not necessarily wanting to be told how but either what to Google for or where to find it.

my local clients connected to the IPv6 internet.
I've already designated a machine to act as the router to the hurricane electric tunnel. I created a he-ipv6 device on it and can ping ipv6.google.com. No problem.
The problem happens when I want clients to use that router. That is, I can't ping ipv6.google.com from other machines on my LAN.
I setup /etc/radvd.conf, which seemed to successfully give out addresses to my clients:
interface eth0
{
AdvSendAdvert on;
prefix MY:HEREFIX::/64
[Code]....
I start the daemon and check that my clients have new ip6 addresses. So far so good. On my router, I do a sysctl -p and see that /proc/sys/net/ipv6/conf/all/forwarding = 1. I haven't touched ip6tables/iptables yet. Both are in a flushed state.
My ipv6 router is actually inside the LAN which gets internet from another machine which has let ipv6 packets through using protocol 41. I figure I don't have to worry about anything else because if my router can ping6 ipv6.google.com, the failure point would be there.
So my clients get ip6 addresses, but can't ping6 the router nor the ipv6.google.com. They do resolve ipv6.google.com however and I checked the traffic on the router over he-ipv6 from ifconfig and RX and TX bytes were changing during the ping.
My router has only one physical device for forwarding, eth0 and the tunnel device he-ipv6. Do I need to add some kind of ip6tables to see a simple ping from my clients?

I set up a static IPv6 address and a gateway in /etc/network/interfaces. However, a bad router in my network environment alway send wrong ICMP router discovery messages to me. So I have got extra (wrong) IPv6 address and gateway, and the routing is confused. On Windows Servers, I can use "netsh interface ipv6 set interface "Local Area Connection" routerdiscovery=disable" to disable ICMP router discovery. But I don't know how to disable it on Ubuntu 9.10. How could I disable ICMP router discovery for IPv6?

I have two network cards in my computer (Debian). One (eth0) is connected to the router which is connected to the internet, the other one (eth1) is connected to my laptop (Gentoo). Now I want to surf the web both on my computer and on my laptop. I obeyed some tutorials "Linux as router":
1. On my Debian system IP-Forwarding is on:
Code:
takada:/home/sam# sysctl net.ipv4.ip_forward
net.ipv4.ip_forward = 1
2. Laptop has IP 192.168.0.2 and this is the output of 'cat /etc/network/interfaces' on my computer:
Code:
takada:/etc/network# cat interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
But a ping from my laptop to 192.168.1.1 (router to internet) still gives:
Code:
connect: Network is unreachable

I am using centos box as a router. WAN side has a public ip and lan side also using a public ip. I configured dhcp server on the LAN side and it is working perfectly, pcs on the LAN side can able to access the internet.
Problem: Considering the fact that LAN IPs is using Public IP and it is presumed that from the internet it can be able to ping IPs inside the LAN but, alas, it couldn't.
No firewall has been config!
Question: What config should be done on the box so that IPs inside the LAN can be ping from the internet?
