How to allow outgoing connection to a specific IP address?
In order to open an outgoing connection to a specific IP you need to add that IP and the IP's mask to the list of allowed IPs. To do that -click on the Add IP Address button and then type the IP address in the 'IP/mask:' field of the form. Also, if you want to open an outgoing connection to an SMTP server at port 25 you need to tick off the 'Allow port 25: (SMTP)' checkbox. Optionally, you can add an informative description of the service that you're about to connect to through this IP.
