I have a question regarding gateway connections. So I have one 2k12 R2 server with RD gateway,connection broker and web access on it. I plan set up a second server to load balance gateway/web and also HA for connection broker.
Currently on the gateway, connections are coming as HTTP only on the gateway. Externally, I do not have UDP open right now. We have around ~250 connections going simultaneously.
I was going to wait till add a second server to open up UDP. Opening up UDP(3391) will triple the connections shown in the gateway.
Should I go ahead and open UDP now? or wait till I add second server to be safe?
Thanks.
