Security after port configure
 

I finally got my P2P working by using port forwarding in my router and authorizing the TCP and UDP, incoming and outgoing, port 6346 in my firewall. Now the question then is, is my computer still safe? If I have opened up port 6346 and the client is running then I should be OK because that program will be occupying the port. But what about when it's off? Will I be vulnerable to threats via the open port? Is this something I should turn on and off as I use the program?

Most Firewalls have the ability to allow ONLY that program to access a particular port.


If you tell us what Firewall you have, maybe someone can find a walkthrough for you. :)

I use Zone Alarm Pro. And I think I answered my own question. I disabled the open ports within the firewall and just granted the program permission. (while still keeping the port forwarding) I then ran a port check through GRC.com and it had full access to the ports.

So, I then shutdown my client and tried it again. This time no access to the ports. Looks like I may need to get peer guardian after all.
