Sometimes, Firewalls Block the Good Stuff

Although firewalls are intended to always block the bad stuff, while letting the good stuff through, it is not always that easy. Sometimes as a side effect of having a firewall, a program you want to access the Internet does not function properly.

The best approach if you suspect the firewall is causing the problem is to temporarily turn off the firewall and determine whether the program now functions. If it does, turn the firewall back on and adjust the access settings for the program. Peer-to-peer-sharing and file-transfer/FTP programs are the most common for this type of problem.

Very Important

Always remember to turn the firewall back on if you temporarily disable it to debug program access control issues.
