Hello: Have you tried to see if there is something wrong in the routing table ? (try netstat -rn -A inet6 or something like that to see the IPv6 routing table)
Moreover, a "tcpdump" on the router can help you to find out what's wrong. At first sight, I don't see anything wrong with your configuration :( > [EMAIL PROTECTED] wrote: > > Help please... > We have IPv6 pc-gateway problem.. > > RH7.2 + Kernel 2.4.18 > > The Network configurations : > > eth0 eth1 eth0 eth0 > Host1 ------------ GW1 ------------Host2 > > Host1 eth0 - 3ffe:2e01:1:3::1/64 > > GW1 eth1 - 3ffe:2e01:1:3::2/64 > eth0 - 3ffe:2e01:1:4::1/64 > > Host2 eth0 - 3ffe:2e01:1:4::3/64 > > ==== >> Problem : GW1 can not forward packets from Host2 to Host1 and > Host1 to Host2 > > We tries the following.... > > kernel settings : > > . ip:advanced router yes > .
