Title: Tunnel routing not working
Post by: tjpeters on July 08, 2011, 02:13:39 AM
Hi,

I have setup my first tunnel, so this could be a noob error.

I can ping the tunnel server and v6 DNS server from my router, but I cannot ping he.net or ipv6.google.com.
From my LAN assigned /64 I can ping my router, but not the tunnel server, so I think I have a routing issue.

Ping tests below
ping tunnel server
dsl-1#ping 2001:470:1F08:17C7::1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2001:470:1F08:17C7::1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 36/37/40 ms
adsl-1#

ping v6 dns
adsl-1#ping 2001:470:20::2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2001:470:20::2, timeout is 2 seconds:

ping he.net
adsl-1#ping 2001:470:0:76::2

Type escape sequence to abort.

ping ipv6.google.com
adsl-1#ping 2a00:1450:400c:c00::67

Any help would be greatly appreciated

Problem solved by creating a completely new tunnel.

Will delete old configuration
