Odd. I had to go through a learning curve when converting my system from InterMail/Irex to Binkd, but that had to do with the conversion from AMA to BSO. IPv6 (both incoming and outgoing) worked from day one on Binkd.

That is unsatisfactory. If you do not know what the problem was, it may come back any time. :(

I tried to use WinXp SP3 as a router for IPv6 but I quickly abandonned that plan. My AYIYA SixXs tunnel ends on the Fidonet machine and only servers that machine.
BTW, when I converted to Binkd and dropped InterMail and Irex, I also dropped POTS. Intermail had been listening to the modem all the time, but there were no incoming calls for over three years, so I figured I could do without.
