Can't get collaboration software to connect through the firewall

I’ve installed Kerika, a collaboration package, but can only get it to work when the firewall is disabled. I set Kerika up as a trusted application, but that didn’t seem to help. What am I missing?


I did a little research on this program and found on one of the Kerika support pages the needed information. The program needs the ports 10421 and 10422 to be open for incoming traffic. I assume that these ports need to be both open for TCP and UDP protocols. The specification I found does not state this specifically.

To open the port TCP 10421 and 10422:

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 or UDP
Direction: In
Description: Incoming Ports Kerika

Source address: Any
Destination Address: Choose MAC address and fill in the found MAC/Physical address
Source Port: Any
Destination Port: choose a port range and fill in 10421 and 10422

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.
