Firewall rules and VPN

[ron]

Hello Omar,

I assume you mean you have a VPN over PPTP with Windows machine those
using data transport via the GRE 47 protocol port 1723.
This is mostly used by Cisco VPN's.

I think the problem lays in your kernel, by default your kernel isn't
compiled for it.
There are packages at sourceforge PPTP project ( "sourceforge.pptp.org"
I thought) you need to compile the kernel for supporting this GRE47
protocol.
This project will help you to follow the steps, the docs are very clear.

Success
Ron

However, when it start verifying username and password, the connection does not go through.  Please if any one have done this before, give me the idea how I should this be done.
