need a really simple tutorial

need a simple tutorial on how to allow programs through the firewall just some games were people are being blocked from playing i know its comodo as they can join when i disable the firewall and cant seem to allow these games to work properly any help on this ?

Easiest is to give the game executable the Trusted Application policy.

Then edit the Global Rules to open one or more ports for incoming traffic.

Read the following tutorial I made. Substitute the port numbers and protocol for your situation.

To open the port TCP 1723 for example

First step is to determine the MAC or Physical address of you network connector. Go to Start → Run → cmd → enter → a black box will show up and enter the following → ipconfig /all (notice the space before /all) → enter → now look up the Physical address and write it down.

Notice that Physical address = MAC address

Firewall → Network Security policy → Global Rules → Add → fill in the following:
Action: Allow
Protocol: TCP
Direction: In
Description: Incoming Port

Source address: Any
Destination Address: Choose MAC address and fill in the found MAC/Physical address
Source Port: Any
Destination Port: 1723

Then push Apply → Now make sure that the new rule is somewhere above the basic block rule(s) as the bottom (the block rules have red icons); you can drag and drop the rules → Ok.
