VPN PPTP through ubuntu iptables firewall

[Guest waleedoo]

Hello guys

 

I have set up a windows VPN server behind Linux - Ubuntu box that is working as firewall and proxy server. Now I want people from outside to be able to connect to the VPN server, but the connection is not being established and I get on the client an error 619. I have checked the problem on the internet and it seems a firewall issue.

 

here is below the information about my setup

Firewall-External-IF-IP: 172.16.1.100

Firewall-LAN-IF-IP: 192.168.1.1

VPN-Server-IP: 192.168.1.10

 

So what can I do to allow VPN connection to pass through Ubuntu iptables firewall to the VPN Server.?

 

hope that I find the solution here ....!!
