Just read your discussion with Matt and Rembrandt on DragonflyBSD list
on OpenBSD's PF issues.
Although I can't afford to restore the configuration to test the
issue, but I feel, that problem could be connected to IPv6 +
The machine we've tried to connect from was running Vista. AFAIR, it
tries to make some use of IPv6. Can't tell anything on XP or other
clients - never tried that.
OTOH, outgoing PPTP (IPv4) session from MPD4 to some HW VPN router
(sorry, anonymous to me) was just fine.
Hope this helps.
I can't upgrade ATM, but still can supply config files if needed.
