Tested the patch on a 4.0S system against KRB5 tunnelled through VPN (pipsecd for now) then NATed (using IP Filter at the remote side) to my employer's network. Kerberos rlogin and KRB5 telnet now work however KRB5 ftp still has problems. KRB5 works nicely with or without the patch when directly connected via PPP to my employer's network, e.g. no VPN and no NAT. (This opened up another can of worms when I disconnected PPP from work and tried to reestablish routes through VPN through the cable modem... but I digress onto a tangent of something else that might be broken when IPv6 is in the kernel and as it's late, I don't want to go there right now. Maybe some other day.) KRB5 works nicely through VPN and NATed without the patch without IPv6 in the kernel. As IPv6 is not an issue for me at this time I haven't aggressively pursued a solution, however I am willing to help out with testing and debugging when time permits. In summary, the patch is a huge step in the right direction. It could very well be that KRB5 ftp may be at fault, not IPv6 in FreeBSD. I don't know at this time.
