VPN get disconnected once trying launching VDA Desktop


Asyraf Mohd

Question

Hi, my client facing issue when trying to launch VDA using VPN connection (Third Party VPN- Ivanti), the VPN get disconnected
- The issue occur only when using VPN connection. If accessing using internal network, no issue occur. Already check at VDA event viewer, can see the user session is already inside the VDA but due to VPN disconnected, resulting the Desktop launching unable to fully established. User able to access storefront but get disconnected when trying to access/launch application. This setup is on-prem setup, no ADC is configured. The main target is Citrix App able to launching using the internal Network only.

Test that already perform (Using VPN) :-
- machine A (able to access & launch VDA/Application)
-machine B (able to access storefront but unable to launch VDA/Application (workspace is active) but session disconnected due to VPN get disconnected )

-User group A & B launch using machine A, no issue occur.

-User group B & A launch using machine B, (able to access storefront but unable to launch VDA/Application (workspace is active) but session disconnected due to VPN get disconnected)

-Verify that the User group A and B is using the same group policy.

-RDP direct to the VDA server is success while using VPN connection.

 

Does anyone facing this kind issue?

Hi @CarlStalhood,

 

Thanks for your respond. 

 

Is EDT (aka Adaptive Transport, UDP) enabled? Yes, we already test bypass the firewall by turn it off.

 

Does the VPN require a reduced MTU? From VPN vendor side, they already bypass everything. by putting all setting to Allow/any/default

 

Another testing is, we use a fresh machine(format), no issue at all, the user group A & B able to launch application. But management wont approve this due to big number of user.
