Trouble with Citrix Secure Gateway on DMZ
Hi All, I am trying to fix our Citrix Gateway. We have two Citrix Server(XenApp 6.5) on the 88.8.0.0/16(LAN1) subnet and works great.
We also have a Citrix Secure Gateway on the DMZ on a 99.9.0.0/16 subnet.
If I move the CSG from DMZ to LAN1everything works as intended.
By going to https://CSG/ I get the web login portal and able to log in and launch applications.
When the CSG is on the DMZ it does not work. I get to the login portal but that is about it. It does not authenticate any user.
I tried setting up access rules on the Sonicwall to allow traffic from CSG to Citrix Server over Port 8080 and 443.
Then as a Test I allowed all traffic on all ports to hit the citrix servers. I check the packet monitor on sonicwall and it shows it passing traffic to the Citrix Servers but still not able to login.

Go to page 636 where it starts on using the CSG in a DMZ. In both examples, it shows that the Web Interface is also in a DMZ.

Is Web Interface installed on the CSG server?
Can you post screenshots of the output of the diagnostic report (you can blur sensitive info)?

Hi Carl,
CSG Server: Has WI and CSG Installed
CITRX 1: Has XenApp and WI Installed
CITRX 2: Has XenApp and WI Installed
Hi Sam,
Headed to the other office for a meet. I'll send a screen shot as soon as I get there.

Hi Sam,

Not exactly sure why WI is on the XenApp and CSG. Just trying to clean it up and make it a bit more secure. Currently they are Port Forwarding directly to the XenApp\Webserver Server. Found the CSG but wasn't fully configured so trying to get that up and running.
I think the best bet it to just rebuild the whole Citrix Enviroment on Hyper V. Sound like I should spin up another server for WI and put it in the DMZ with the CSG?
DMZ:
CSG
WI
Lan:
XenApp1
XenApp2

You can put both CSG and WI on the same server. If you have a second CSG/WI server, you could load-balance the two of them for failover..
Typically WI is installed on the same server as CSG (and makes it easier to configure in my opinion and one less server in the DMZ).
Unless Sam disagrees (Sam and I are friends and fellow CTPs), I would just uninstall WI and IIS from the existing XenApp servers to save you the trouble of building new servers and installing and configuring applications.

This is going back quite a while, but if I remember correctly, uninstalling IIS from a XenApp server can sometimes cause issues with the XML service.
I would suggest just leaving it, and building a second CSG/WI in the DMZ (for load-balancing and failover).
Better yet, I would highly suggest upgrading to StoreFront and NetScaler Gateway for security reasons.

Hi all,
Thanks to your help guys I was able to get the server working as intended. I am putting into budget to get us up to the latest Version of Citrix. I saw the Citrix Workspace demo video and was drooling. lol.
