[Firestarter-user] Help Understanding Why Firestarter is blocking y VPN connection to Hidemyass Proxy VPN server!

[Mike E. <mi...@ch...>]

Hi, I just started using the web proxy service Hidemyass with my Ubuntu 
12.04 box. I have set up the vpn connection in "Network Connections", 
however, I only get a successful connection if I stop the firewall with 
Firestarter. I have read lots and lots of forum threads and tried lots 
of different settings but every time I start the firewall the connection 
drops and every time I stop the firewall it works! I just can't find 
accessible information regarding how to set-up Firestarter to let the 
vpn connection through.

My current set-up in Firestarter is:

In the "Policy" tab > "Inbound traffic policy" > "Allow connections from 
host" > [my vpn IP address]

In the "Policy" tab > "Inbound traffic policy":

Allow service: unknown
Port: 1723
For: my vpn IP address]
In /etc/firestarter/user-pre (i.e., $ sudo gedit 
/etc/firestarter/user-pre) I am using the following settings.

  # Forward PPTP VPN client traffic
$IPT -A FORWARD -i $IF -o $INIF -p tcp --dport 1723 -m state --state 
NEW,ESTABLISHED,RELATED -j ACCEPT
$IPT -A FORWARD -i $IF -o $INIF -p 47 -m state --state 
NEW,ESTABLISHED,RELATED -j ACCEPT
$IPT -A FORWARD -i $INIF -o $IF -p 47 -m state --state 
NEW,ESTABLISHED,RELATED -j ACCEPT

I'm really stuck with this. Any help would be really appreciated.
