Firewalling for the NVidia ActiveArmor Firewall






 

Before we can open ports for BCDC++, we need to figure out what ports BCDC++ is using. Here is a brief walkthrough on how to do that. Go ahead and open up BCDC++.




In the menu at the top of your screen click the file option. In the menu that drops down click the Settings link.




In the menu on the left hand side of the window that popped up click the Connection Settings link. You should see a TCP box and an UDP box. Enter a random port into each of these boxes. It doesn't matter what ports you choose, but a port numbers between 10000 and 60000 would be a good idea. A higher numbered port is generally the best to use, because most ISP's do not block the higher numbered ports. Please enter the port you chose for the TCP box into the box below.

BCDC++'s port for incoming TCP connections



Please enter the port you chose for the UDP box into the box below.

BCDC++'s port for incoming UDP connections

I've heard of and experienced this firewall causing "out of memory" errors with some programs. Just be aware of that when using this firewall. Go ahead and open up the Nvidia ActiveArmor Firewall.


Click the View the current Profile link.


In the main section of this page change the Security Profiles to one of the custom configurations. Put a dot in to the Re-generate profile based on radio button. I chose medium here, but you can choose any of the profiles to base your custom profile off of. Then click the Apply button at the bottom of this page. You should see a status page as the firewall generates the custom configuration settings. When it is finished you should find yourself back at the Firewall Basic Configuration Page. Now click the Firewall link on the left hand side of this page. Then click the Advanced Configuration link. Then click the UDP/TCP Port link in the left hand menu.


The default TCP/UDP port inbound action drop down box should be set to deny. Click the Add button on the bottom of this page. Then enter the settings as shown below.
