I am running monowall version 1.22 with a PPTP VPN setup. I just upgraded my computer's security program from AVG Internet Security 7.5 to AVG Internet Security 8.0. Well, due to the nature of the upgrade, it wiped out all my firewall settings on my laptop and made me start over from scratch.
When I went to connect to our company VPN today from home, I could not connect at all. So I quickly figured out that it was due to the fact that I had to re-setup my client firewall rules to allow PPTP VPN on TCP out remote port 1723 and also had to allow GRE on protocol 47 going both in and out.
So now when I try and connect to the VPN, it is able to connect, but when it goes to verify the username and password, it returns with an "error 619: A connection to the remote computer could not be established, so the port used for the connection was close"
The only way I have found to make the VPN work is change my firewall zone to "Allow All" which allows the VPN to verify the password right away. The problem is that I do not want to leave my client firewall in the "Allow All" zone for many reasons.
What am I missing here? Is there a different port that the auth for the username and password works on that I have not allowed to pass? I've been working on this all morning and I am at my end on this. Any help that anyone can give would be great.
My client is running Microsoft Windows XP SP 2, and is using the built in VPN connection stuff to connect to the office. Also, this worked fine before upgrading to AVG 8.0.
