I can confirm full IPV6 connectivity from HE.
I'm using the HE tunnel also and it works fine.But I have a bit of difficulty getting the right ip6tables (and the single iptables) rules to work so that my one server that tunnels ipv6 can serve as a gateway server.
I used http://madduck.net/docs/ipv6/ as a guide.Using tcpdump I can see a ping from a server behind the gateway going to the gateway server and the gateway server sends it to the tunnel, but nothing's coming back.
i.e.: behind gateway: # ping6 2620:0:2d0:200::10 PING 2620:0:2d0:200::10(2620:0:2d0:200::10) 56 data bytes ^C --- 2620:0:2d0:200::10 ping statistics --- 392 packets transmitted, 0 received, 100% packet loss, time 391484ms gateway: # tcpdump -t -n -s 512 -vv ip6 or proto ipv6tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 512 bytes IP6 (hlim 64, next-header ICMPv6 (58) payload length: 64) 2001:470:85cd:0:20c:6eff:fed2:1947 > 2620:0:2d0:200::10: [icmp6 sum ok] ICMP6, echo request, length 64, seq 317 IP6 (hlim 64, next-header ICMPv6 (58) payload length: 64) 2001:470:85cd:0:20c:6eff:fed2:1947 > 2620:0:2d0:200::10: [icmp6 sum ok] ICMP6, echo request, length 64, seq 318 IP6 (hlim 64, next-header ICMPv6 (58) payload length: 64) 2001:470:85cd:0:20c:6eff:fed2:1947 > 2620:0:2d0:200::10: [icmp6 sum ok] ICMP6, echo request, length 64, seq 319
Anything obvious I might have missed? Can post more specifics later if needed.
