The OS thinks you have IPv6 connectivity because something on your network is sending IPv6 router advertisements for a default IPv6 route. This is probably the AirPort Extreme. It's probably in NAT mode, and your cheapo Trendnet router isn't actually routing; it's just bridging between ethernet and Sonic's DSL link.

No, it's the router that's acting as NAT and DHCP server; the AirPort Extreme is just in bridge mode. (I do this because I have some clients on Ethernet only.)


The IPv6 setting on the AirPort is set to Tunnel mode, Automatic IPv6 configuration, Block incoming connections. I don't know whether I meddled with that in the past, or if it came that way. I'll set the mode to Link-local only and see if that helps.
