Team,

I'm looking for an ACL rule that limits VoIP traffic from a specific external source IP and a specific internal destination port.

While realizing that the return path is vice-versa => I expect at least 2 ACL-entries - like for example:

Block all packets where "source-IP <> 1.2.3.4 and destination-port = 5060"

Block all packets where "destination-IP <> 1.2.3.4 and source-port = 5060"

The default ACL is permit-all - meaning allow rules are not very helpful since it is already allowed?

And block rules don't have this "not equal to"?

Any suggestions how to make this happen?

With warm regards - Will
