Here's the scenario.
I have a client with an old Citrix farm (PS4.5 + CSG 3.1),
On doing some discovery about the network I discovered that all their Citrix connection traffic coming from the web interface goes through a CSG, whether it's internal or external. This CSG is under lots of load and is struggling to cope with it as it's old hardware ... After doing some reading I found that there are DMZ settings within the web interface settings that should allow me to point internal IP range directly to the server, and external IPs to the CSG.
I configured the settings as so under the "Edit DMZ Settings" window (cant post an image):
Client IP | Mask | Access method
172.16.0.0 255.255.0.0 Direct
Default Gateway Direct
However, in this setup all connections are still going through the gateway. I know the settings are actually applying because if I change the default to "Direct", external access stops working (!).
Does anyone have any advice on this? This setting doesn't seem to do what it's supposed to :(
