Hi. I want to use pptpd and gShield on the one router mashine.I have two network cards eth0 and eth1. gShield work correct and it NAT correctly connections from OUT to IN net. When gShield is stoped pptpd work correct and I can connect to it from IN and OUT cards.
Unfortunately when I start gShield firewall, connections to VPN from OUT ethernet is blocked even when I put "OPEN" option in PPTP section! I can connect ONLY from IN cart but I have some mashine which must connect from Internet - OUT card.
When I start gShield it log:

PPTP publically accessible.
Opening port 1723

but I saw that port 1723 is closed even when I put it in /conf/open_ports file! I do not have another firewall applyed.
I read a lot of documentation about this but I couldn't fount ansver....
Can somebody help me how to configure gShield to allow me connections to PPTPD from card which is connect to Internet?

Hmm it is closed even SSH.... Really strange.
Some ideas.
