##### Cannot get tunnel up
« on: January 09, 2011, 11:18:10 AM »

I have a Windows Server 2008 R2 Enterprise machine running on vmware.

I have a Linksys WRT54G router so I put 192.168.1.42 in the DMZ.

Used these commands on the 2008 VM:

netsh interface teredo set state disabled
netsh interface ipv6 add v6v4tunnel IP6Tunnel [removed] 72.52.104.74
netsh interface ipv6 add address IP6Tunnel 2001:470:1f04:1632::2
netsh interface ipv6 add route ::/0 IP6Tunnel 2001:470:1f04:1632::1

If I try to ping 2001:470:1f04:1632::1 it returns "General Failure" however if I ping 2001:470:1f04:1632::2 it responds fine. Where did I go wrong?

I am a networking newbie but I thought that since I put the machine in the DMZ, I was supposed to use the public IP. Am I wrong?

You need to use the nated address not the public address.

So what were the commands you put into the command prompt window?

If you used the nat address and your tunnel still isn't working, that must mean that protocol 41 isn't getting passed to your host.  Have you looked at traffic yet?

As above, although I switched my public IP with my server's internal 192.168.1.42.

I thought by putting it in the DMZ, I wouldn't have to worry about protocol 41 not being passed... Oh well. Time to flash my router with DD-WRT.

edit:

Tunnel is up after flashing my router to DD-WRT. I guess putting it in the DMZ means nothing. Thanks for the replies.
