Question

Contoso deploys a pooled host pool for on-premises employees who connect over an ExpressRoute private connection. Users report that sessions still use the TCP-based reverse connect transport instead of the lower-latency direct UDP path. You want to enable RDP Shortpath for managed networks so clients establish a direct connection to the session hosts. Which configuration must you apply to the session hosts to allow this direct connection?

Accepted Answer

Enable the RDP Shortpath listener and allow inbound UDP port 3390 on the session host firewall and network security group

Answer

Open inbound TCP port 3389 on the network security group and disable reverse connect transport

Answer

Configure a STUN/TURN server relay and allow outbound UDP 3478 from the session hosts

Answer

Assign public IP addresses to the session hosts and enable UDP port 443 on the load balancer
