Note: When posting log details on the forum, it’s possible they may contain references you your external IP Address. (The IP Address shown in the bottom right of your forum post) In consideration of the privacy issues related to this, we ask you to modify any reference to your external IP Address in the log, using the following example:

Your Address: 123.245.789.123
Modified Address: x.x.x.123

Some things to consider:
Network Monitor rules are hierarchical, that is, they work from the top down. Therefore, a BLOCK rule placed above an ALLOW rule will take precedence.

If you’re having problems with a specific application, check Application Monitor for a rule that BLOCK’s that application.

• When installing Comodo Firewall please disable other programs. If you don’t there will be some interference later on that you may never know. Installing in Safe Mode is one way to ensure you don’t have other software running.

• Always uninstall other software firewalls before using Comodo Firewall. Simply disabling a firewall is not the same because the 2 will conflict! (Windows firewall is the only exception). This has proven to cause strange issues, so please never run 2 software firewalls together.
