It was running rtadvd to hand out IPv6 addresses from my sixxs block to the network. However, after migrating this configuration over to a newly installed FreeBSD 7.2 box it appears that the machine will no longer route IPv6. All the correct settings seem to be enabled as described here: http://www.freebsd.org/doc/en/books/handbook/network-ipv6.html, and the configurations are identical to the 7.0 box. The only odd thing I can see is that the machine is not getting an IPv6 address on the lan-facing interface, which would explain why it can't route anything. There are no issues with the sixxs tunnel itself or IPv6 connectivity from the machine; it is also handing out IPv6 addresses to hosts on the network via RAs. Could there be something I'm missing? rg -- rob.gallagher (at) gmail.com || www.spoofedpacket.net || PK: 0x1DD13A78
