I have configured PPTP redirect using the m0n0wall GUI. About everything works fine and inbound PPTP connections are being redirected to the PPTP server behind the firewall. Although, when trying to connect to external PPTP servers from within the local subnet, it seems like they are redirected to the local PPTP server somehow, because they never get through.

I could get around this by disabling PPTP redirecting and instead setup a NAT rule that forwards all traffic to port 1723 to the local PPTP server. Unfortunately this introduces a new problem; PPTP connections to the local PPTP server timeout quickly, when idle for a few minutes.

For me it's ok to use any of these methods, I would just want to get rid of either the "outbound PPTP" or the timeout issue.

m0n0wall version 1.231 (generic-pc-cdrom, built on Sat Apr 7 10:51:50 CEST 2007)

Happy for any suggestions or solutions and thanks in advance! Smiley

Never heard of that. What you might be seeing is one machine being able to connect, then no further ones being able to. That's a limitation of the NAT used in m0n0wall, only one machine can connect to any external PPTP server simultaneously.

  Does this mean that when behind a m0n0wall only one person can establish an outgoing PPTP session ? Sounds weird.....

I'm pretty sure the problem is something with the PPTP spec and not m0n0wall specific. I have run into numerous routers that cannot handle PPTP correctly.

One outbound PPTP session per remote server per public IP. If you only have one public IP, that means only one machine simultaneously per outside server.
