[6bone] IPv6 via NAT - problems

[Jeremy Worrells]

Unfortunately, 172.16.0.4 is on a non-routeable subnet that I am using. I
tried using 172.16.0.4 as my address, but freenet6 throws away any request
using 10/8, 172.16/12, or 192.168/16 addresses, as it's not routable. I
thought that using my DSL router's address would let the packets be NATted
and work just fine.
