We need to connect a couple of clients separately to an PPTP-Server.
[PPTP-Server]---WAN (internet)---[m0n0wall 1.2]---[Clients connecting]
The effects are very strange but not as desired. Sometimes one client
can connect while the others can't. It seems to be possible to connect 2
clients if one is using the DNS-Name and the other one the IP-Adress of
We only connect the right side of this picture.
The m0n0wall has got a rule at the WAN-interface allowing GRE from
anywhere to the LAN.
Any idea what I did wrong? Is this a general problem using m0n0wall? I
remember a m0n0wall-Installation where PPTP from behind simply did not
work at all.
We have got an alternative setup using routers and firewalls based on
normal FreeBSD. That way it works.
