Unable to Create Firewall Rule with Port Alias.
-
I'm trying to redirect a port over VPN. I created an alias with the port I'm wanting, but when I try and configure a firewall rule with it, it doesn't autocomplete like my other aliases. When I manually type it I get a message that it is not a valid IP address or alias.
I don't have these issues with IP aliases. Is it not possible to create a firewall rule for a port?

Screencaps?

Sure thing!

You're entering your port alias into the source address field. Change the protocol from "Any" to "TCP", "UDP", or "TCP/UDP" and you'll see a blue "Display Advanced" button appear, which will allow you to specify source port via alias or otherwise.
-
So, creating an alias is not necessary if I want to create a rule for a specific port? I only need to create an alias with the systems I'm wanting to use that port with? Sorry if I'm not understanding.

That's correct. If the rule only contemplates a single port, here 55930—then you need only enter 55930 in the correct field.

Thank you for the help.

Shot in the dark, but you're probably also needing 55930 as the destination port, not the source port.
You're welcome. We'll all be here if follow-up is needed as you make more progress.
