Remote Desktop Manager not showing UDP connections on my 2012 R2 gateways. UDP 3391 is enabled and open externally through a Nat.
I do have two gateways that are load balanced using Microsoft NLB. UDP is enabled on both gateways and VIP is NAT'd in the firewall with 443 and UDP 3391 open. I have seen randomly that a UDP will show up in the manager, but only one. I expect to see an http connection along with two UDP connections.
Is there a reason why I am not seeing the UDP connections come in, or only seeing them randomly? I have it working on the other gateways but they are not load balanced and single gateway instances. It doesn't seem to be related to policy or anything.
I'm thinking about reinstalling the MS NLB.
