Group Policy Layer 3 Firewall Rule Comma Separated Ports?

[Kyojuro]

I thought you could make a firewall rule with comma separated ports? 

Or is this not possible in group policy? 

Attached image is the error I'm getting. All of the ports in the comma separated port list are in the range of 1-65535.

You can use port-ranges in the group-policy, but comma separated lists are IMO only valid on the "general" L3 firewall.
