How do I get my VPN to work even when my firewall is active?

Question

I have subscribed to a VPN service, but it seems that it does not work whenever my firewall is active.

I have up until now used Firestarter to configure my firewall, but it has no options for allowing a VPN connection. Nor does gufw.

What do I do to keep my firewall active, and still be able to connect to my VPN?

Thank you for this suggestion. It does look promising, but the instructions in that link are very heavily tied to using VPNC, which I am not using. A more general solution would be good.

Found a solution that works with Firestarter.

I use OpenVPN, so I opened /etc/firestarter/user-pre and added the following lines:

# Allow traffic on the OpenVPN inteface
$IPT -A INPUT -i tun+ -j ACCEPT
$IPT -A OUTPUT -o tun+ -j ACCEPT

Then I restarted the firewall. Stopping it and starting it within the Firestarter interface seemed to suffice.

The solution was here.
