I just installed Utorrent and tried downloading a file which was successful. I didn’t have to go through the tutorial, I checked network security policy, its added itself in there and its also added itself into computer security policy. Both network defense & proactive defense are running in safe mode, and have been since I installed Comodo Firewall. Do I need to check over the rules Comodos done automatically? Add the ones in the tutorial. Sorry I don’t really understand why its done this as I’ve installed Utorrent before on an XP machine, tried to download a file and Comodos either blocked Utorrent from downloading or restricted the download speed.

Assuming you already opened port(s) on your routre or have Universal Plug and Play (uPnP) doing that. You also need to open port(s) on the firewall for incoming traffic. Read the following for reference; it will give you the clues how to do so.

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 → Advanced → 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.
