my ipv6 details are here (from my sixxs.sh script)
Code:
#!/bin/sh

when i as root, type sixxs.sh start it starts fine, no error messages
Code:
[root@localhost root]# sixxs.sh start
SIOCSIFADDR: File exists
SIOCADDRT: File exists
RTNETLINK answers: File exists
Enabling IPv6: [ OK ]yet if i try to ping the ipv4 of my tunnel broker it works, but if i try to ping6 my tunnel broker, it fails.
i have correctly used IPTABLES on the router (in my case smoothwall) to route protocol 41 and this has worked fine for some time, just stopped yesterday and wont come back
any advice from anyone ??
Quote:[root@smoothwall root]# iptables -t nat -I PREROUTING -p 41 -j DNAT --to-destination 192.168.0.117[root@smoothwall root]# iptables -I FORWARD -p 41 -j ACCEPT

not sure about all tunnel brokers.. but i think you might have to forward protocol 41 to make it work if you are behind a NAT

i've done that dude (its in the post) ;)
i believe its my tunnel because it started working again all by itself magically
