Firewall – WatchGuard ‘Internal Policy’ intermittently blocking outbound web traffic

firewallwatchguard

I have a lot of legitimate outbound traffic intermittently being denied by WatchGuard's "Internal Policy." Today I tried to go to Splunk's homepage and my traffic was denied by my watchguard XTM 22 with Pro upgrade.

What is the "Internal Policy" and what can I do to control it?

Example of Traffic being blocked

Type    Date            Action      Source IP   Port    Interface       Destination IP  Port    Policy  
Traffic 2011-09-21T18:24:43 Deny    10.0.0.90   49627   3-Primary LAN   64.127.105.40   80  Firebox Internal Policy http/tcp

The first firewall policy is "Deny any traffic from 10.0.0.90", so that's what it's doing (your source IP is 10.0.0.90 in the deny message).

Policies are applied from top to bottom, and denies before allows, so that policy matches, denies the traffic, and no more are looked at.

What can you do about it? Change the policies.
