Opening Port

Comodo Internet Security - CIS Firewall Help - CIS
#1

Good Evening Guys and Gals,

I am trying to open ports on my router and software firewalls. I am running Comodo Internet Security Premium 5.3.175 and using Belkin Router F5D9630-4Av1. I have opened the ports on the Router fine using the Virtual Servers option as it says on Belkins website, and I think that I have opened them successfully on Comodo but not 100% sure as the guide on portfoward.com is for an older version of Comodo and is COMPLETELY different, I had a look on the Comodo website but not 100% sure if I had the right section but tried it anyway. But still seem to get a blocked notice when using the portforward.com PortChecker software. I have also set a static IP for all my computers operating so there is no IP conflict, and the IP I used for the virtual servers is the one for my laptop. When I disable the router firewall it seems to work (according to the portforward.com PortChecker software, I have also tried placing my IP in the DeMilitarized Zone (DMZ) on my router to no avail.

I don’t really know what else to try, please help.

Regards,

Dave

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.
