Hi, I have a few rules that only permit ms-rdp and t.120. A new rule was implemented last week that permits ms-rdp and t.120, just different source addresses. The other rule can see the ms-rdp application but for the new rule, it shows up as application not-applicable and the traffic is being blocked. I looked around here for some answers and have found that something before in the rule, the zone/source, etc. could be causing the tcp handshake not complete, thus not allowing the PA to pick up the application. However, the other rule which is working has the same zones set up, just the source address is different (same subnet). So I do not think it is anything to the left in the rule and the other rule is just above it so I do not think that is it either. Just looking for some thoughts/ideas. Thanks!
