Add a single 2001:470:1F00:1979::/64 address each for both fxp0/1. You don't even need rtadv.conf :) rc.conf:- ipv6_ifconfig_fxp0="2001:470:1F00:1979::1/64" ipv6_ifconfig_fxp1="2001:470:1F00:1979::2/64" > > The workstation inside the LAN has the config shown in [2]. > > Checking via tcpdump on the gateway, I can see pings from the client > > hitting the internal NIC (fxp1) and going out the IPv6 tunnel > (gif0). > > In case I've missed something about setting up the tunnel, the > details are [3]. > > Suggestions, comments, thanks. > > [1] Gateway - <http://www.langille.org/tmp/ipv6-config-gateway.txt>; > [2] Client - <http://www.langille.org/tmp/ipv6-config-client.txt>; > [3] Tunnel - <http://www.langille.org/tmp/ipv6-config-tunnel.txt>; -- Ariff Abdullah MyBSD http://www.MyBSD.org.my (IPv6/IPv4) http://staff.MyBSD.org.my (IPv6/IPv4) http://tomoyo.MyBSD.org.my (IPv6/IPv4)
