I have 2 RDS (2012 R2) servers and am attempting to setup load balancing.
RDS1 is the GW, WEB, CB and Session Host
RDS2 is just a session host
Server manager -> remote desktop services overview appears to be indicating that all (but licensing) is setup properly.
I have certificates installed, all DNS records created. The cluster appears to be configured properly (pending licensing). When connecting internally, I am not running into any issues. I have multiple test accounts that when connecting
internally are randomly directed to 1 or the other session host for their session.
When attempting to connect from outside of the network (WAN), if the session is directed to RDS1, the connection is fine. It appears that when the connection is being redirected to RDS2, the connection and authentication process is proceeding, I see"redirecting to..." then it will hang for a moment at "Initiating Connection" and then present the error: Remote Desktop can't connect to the remote computer for one of these reasons:......
I am guessing this has something to do with my firewall rules, but I can't figure out exactly what needs to be done.
I have 3389 TCP forwarding form WAN -> RDS1 (connection broker and gateway)
I have 3391 UDP forwarding from WAN -> RDS1 (connection broker and gateway)
Do I need any rule allowing connectivity to RDS2, or is that supposed to be handled by the gateway/CB?
I have 2 deployments with this same issue, one through a Sonicwall and the other through a Watchguard.
Is this something other than the firewall rules?
I have the RD client set to automatically detect gateway settings. I would like to not have to have all of our users specify this if possible.
Any assistance is greatly appreciated.
