Allow traffic based on protocol

Ali Akbari

Hi all

In my UTM firewall log, I can see incoming MS Teams traffic being dropped. The traffic is coming from a public IP, not Microsoft's O365 IP ranges.

In my rules, I have allowed Microsoft's "high ports" 50000:50059 (the 2nd row for example), but the dropped packet is using a port outside the range.

However as shown, UTM recognises both packets as Microsoft Teams. This column is where it usually says TCP, UDP, ICMP etc.

My question is how can I define a rule using the traffic type? Because normally when you're setting a rule, you can select services which are based on port numbers, not traffic type.

Cheers

Ali
