Why don't you terminate the IPv6 tunnel in the Cisco in the first place? Michel.

I have an Ipv6 island (with router GNU/Linux) and I was trying to make a tunnel for another island to connect it to the 6bone. I did that a couple of times to connect islands which routers with public IPs. Now there is an island behind a nat made it by a cisco router in this configuration: R1(priv IP) R2(publ IP) R3(publ IP) remote -> router IPv6 -> router -> INTERNET -> my_router -> 6Bone island GNU/Linux Cisco IPv6 GNU/L I read the Palet's IST-2001-32161 suggestion of replacing the private address instead public address and left protocol 41 free in the Cisco router, and the admin of the other island put this commands in his IPv6 Linux router: #ip tunnel add <tunnelname> mode sit remote < R3 public IP> local <R1 private IP> ttl 64 #ip link set <tunnelname> up #ip address add 3ffe:xxxx:xxxx:xxxx::2/64 dev <tunnelname> #route -A inet6 add 3ffe::/15 gw 3ffe:xxxx:xxxx:xxxx::1 <tunnelname> I did the usual stuff in my side of the tunnel #ip tunnel add <tunnelname> mode sit remote <R2 public IP> ttl 64 #ip link set <tunnelname> up #ip address add 3ffe:xxxx:xxxx:xxxx::1/64 dev <tunnelname> but I just can do ping6s to my local end of the tunnel, not the remote end. Please any idea of what is wrong?
