How can I add a second host from same WAN IP

ratcheer · February 24, 2011, 10:43:47 AM

Ok, I have reconfigured everything. I hope I have all the obvious stuff correct. It still does not work, though.

New startup script on the router:

Code Select


insmod ipv6
sleep 5
ip tunnel add he-ipv6 mode sit remote 216.66.22.2 local 68.209.199.199 ttl 255
ip link set he-ipv6 up
ip addr add 2001:470:7:b57::2/64 dev he-ipv6
ip route add ::/0 dev he-ipv6
ip -6 addr add 2001:470:8:b57::/64 dev he-ipv6
ip -6 addr add 2001:470:8:b57::/64 dev br0
ip route add 2000::/3 dev he-ipv6
radvd -C /tmp/radvd.conf &

I restarted the router and verified that radvd is running. Here is the output of ifconfig on the client, with ipv6 enabled:

Code Select

Thanks for all your help.

Have you double checked to make sure that 68.209.199.199 is the IP address you put on the HE page for your IP end point?

Yes, and it has been working for several days with the tunnel link configured on my client PC.

Here is from my tunnel details page on tunnelbroker.net:

Client IPv4 address: 68.209.199.199

OK, so something's not making sense.

The tunnel was working at one time...what happened to break it? Or, did it not break and you just want to move it to your router?

ratcheer · February 24, 2011, 10:55:29 AM

I am wondering about the next to last statement in my router startup script. I took it from a tutorial on the dd-wrt wiki. There are no instructions to change it, but should it say "ip route add 2001::/3 dev he-ipv6" instead of "ip route add 2000::/3 dev he-ipv6"?

It did not break. I want to move it to the router because I cannot get radvd to start on my client PC.

cholzhauer · February 24, 2011, 10:58:53 AM

Yes...it would need to be 2000, not 2001.

Some OS's need that, some don't. I don't think you'd break anything by having it though.

ratcheer · February 24, 2011, 11:03:04 AM

Ok. Right now, I am out of time to mess with it anymore. I'm going to take it back away from the router and live without radvd for the time being. At least I have learned a good bit about scripting on the router.

I finally got my IPv6 set up on my router with sharing to my LAN hosts working. Here is what worked for me:

Startup script on router:

Code Select

insmod ipv6
sleep 8
ip tunnel add he-ipv6 mode sit remote 216.66.22.2 local 68.209.xx1.xx2 ttl 255
ip link set he-ipv6 up
ip addr add 2001:470:7:yyy::2/64 dev he-ipv6
ip route add ::/0 dev he-ipv6
ip -6 addr add 2001:470:8:yyy::1/64 dev br0
ip route add 2000::/3 dev he-ipv6
radvd -C /tmp/radvd.conf &

radvd.conf on router:

Code Select

interface br0 { 
        AdvSendAdvert on;
        MinRtrAdvInterval 3; 
        MaxRtrAdvInterval 10;
        prefix 2001:470:8:yyy::/64  { 
                AdvOnLink on; 
                AdvAutonomous on; 
                AdvRouterAddr on; 
        };
};

I hope this might be helpful to others. (My true IP addresses are masked out.)
