I followed the directions here (http://www.dd-wrt.com/wiki/index.php/IPv6) to get my IPv6 tunnel set up, but I can't ping the endpoint. AICCU starts up great and runs, and I have the following device: # ip addr list . . . 43: sixxs@NONE: <POINTOPOINT,MULTICAST,UP> mtu 1280 qdisc noqueue link/sit 216.235.8.211 peer 66.39.212.2 inet6 fe80::d8eb:8d3/64 scope link inet6 fe80::c0a8:501/64 scope link inet6 2001:4830:1500:34::2/64 scope global The IPv6 address of the endpoint is 2001:4830:1500:34::1 but I can't ping it, nor can I access any other IPv6 host using IPv6 (ping or otherwise). The routing table: # ip -6 route ::/96 via :: dev sit0 metric 256 mtu 1480 advmss 1220 2001:4830:1500:34::/64 dev br0 metric 256 mtu 1500 advmss 1220 2001:4830:1500:34::/64 via :: dev sixxs metric 256 mtu 1280 advmss 1220 fe80::/64 dev eth0 metric 256 mtu 1500 advmss 1220 fe80::/64 dev eth1 metric 256 mtu 1500 advmss 1220 fe80::/64 dev br0 metric 256 mtu 1500 advmss 1220 fe80::/64 dev vlan0 metric 256 mtu 1500 advmss 1220 fe80::/64 dev vlan1 metric 256 mtu 1500 advmss 1220 fe80::/64 via :: dev sixxs metric 256 mtu 1280 advmss 1220 ff00::/8 dev eth0 metric 256 mtu 1500 advmss 1220 ff00::/8 dev eth1 metric 256 mtu 1500 advmss 1220 ff00::/8 dev br0 metric 256 mtu 1500 advmss 1220 ff00::/8 dev vlan0 metric 256 mtu 1500 advmss 1220 ff00::/8 dev vlan1 metric 256 mtu 1500 advmss 1220 ff00::/8 dev sixxs metric 256 mtu 1280 advmss 1220 default via 2001:4830:1500:34::1 dev sixxs metric 1024 mtu 1280 advmss 1220 The firewall rules already allow protocol IPv6 through. Any ideas?
