So... I've tried setting this up a million different ways and the furthest I can get is this: ----------------------------------------------- ###### [5/8] Ping the IPv6 Local/Your Inner Tunnel Endpoint (2001:4830:1500:3a::2) ### This confirms that your tunnel is configured ### If it doesn't reply then check your interface and routing tables PING6(56=40+8+8 bytes) fe80::1%lo0 --> 2001:4830:1500:3a::2 ping6: sendmsg: Message too long ----------------------------------------------- Here's my config: ----------------------------------------------- # AICCU Configuration # Login information username ********** (removed) password ********** (removed) # Interface names to use ipv4_interface en1 ipv6_interface sixxs # The tunnel_id to use # (only required when there are multiple tunnels in the list) # tunnel_id Txxxx # Be verbose? verbose true # Daemonize? daemonize false # Automatic? automatic true ----------------------------------------------- Keep in mind here that I can only get this far if I add a manual route like this: ----------------------------------------------- sudo route add -inet6 default -interface gif0 ----------------------------------------------- Final item is that if I do an ifconfig while the test is running, I never see a sixxs interface. Help?!?!?!? :) Sorry for my ignorance in advance. Kind regards!!! -frustrated-
