Hi,

I've had a tunnel to HE which has been working fine since May last year. I've now moved house and am using a different ISP (Virgin cable in the UK) and the tunnel seems to have stopped working. It comes up alright but never receives any packets.

Can anyone help? Let me know what information you need and I'll provide it.

Thanks!

IPv6 on Linux & BSD & Mac / problems after reboot [solved]
« on: July 30, 2008, 01:18:45 PM »
Hi, I've had a tunnel working for the past few months with no problems but the server rebooted due to a power outage yesterday and now I'm having a problem with the tunnel!

After a bit of sleuthing I've discovered that the SIT tunnel seems to work. By running wireshark I can see that when I send a ping packet, it leaves sit1 (my tunnel interface) and is then encapsulated in IPv4 and sent on to the remote host. I can then see the returning echo reply coming down my IPv4 eth1 - but the packet never shows up on sit1.

Since wireshark sees packets before they hit netfilter my first thought was that iptables was blocking the incoming protocol 41 packets but it's not. IPv4 and 6 forwarding are enabled in the kernel but there must be some setting I'm missing that causes the incoming packets to vanish after they're received on the IPv4 side!

Any help would be appreciated - I can provide configs and anything, just let me know what you need! :)

Thanks for any help,
Steve
