Hi. A small issue which I'm struggling to troubleshoot.
Scenario: RDS 2012 farm. Web Access servers (2), Gateway Servers (2), Connection Brokers (2) and RD Session Hosts (3).
Published Applications are varied, 8 of them in total.
Access methods.
Internal networks - RDP client version 8. Working correctly.
VPN Service 1. Web Browser to WA Servers via F5 Load Balancers. Also working correctly. LB is configured for Fast L4 switching, no SSL offload.
But, access method 3 is via a different VPN route. It hits the same load balancers as VPN Service 1, the client is presented with a login (which I believed is cached at this point). From there they are presented with a list of available applications controlled by the access policy. However, when a user tries to launch one of these apps they get a time out. The app doesn't launch. Error message is a generic one - "Unable to connect"
So, the farm would appear to be working correctly and I suspect this is a networking issue. What I can't find is a detailed and sequenced diagram or explanation of the data flows during the whole process, i.e.
Client to WA server on 443 TCP
WA server to GW server on 443 TCP ?
GW Server to CB Server on ?
CB Server to RDSH on 3389 ?
Please excuse my lack of knowledge. I am more a network guy who is trying to help the RDS people but I am not 100% sure of which traffic to look for in the logs.
Thanks.
