/127's that is a *bad* idea. Kernels 2.4.20+ finally started to
implement anycast, though in your case your routing table seems fine,
thus I assume you didn't upgrade your kernel yet ;)
Otherwise you would have ::f00/128 pointing to lo also.

You are behind a NAT, thus I do hope you setup your NAT-box correctly to
forward the packets to the correct host.

You need to forward protocol-41 for this to work. Usually configuring
the real endhost as a 'DMZ host' works.
