Review Rule Parameters

Edit the rule in question and review the parameters for each field. For TCP and UDP traffic, remember the source port is almost never the same as the destination port, and should usually be set to any.

If the default deny rule is to blame, craft a new pass rule that will match the traffic to be allowed.  If the traffic is  still blocked, there may be some other special aspect of the packets which require additional handling in the rule configuration. For example, certain multicast traffic may need to have Allow IP Options enabled, or the log entries may be due to asymmetric routing, or the packets may have an invalid combination of parameters such as a fragmented packet with “Don’t Fragment” set inside.
