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.

Did you run the Secure Gateway Diagnostics Utility? What does it say?

HI Sam, Test Failed at Web interface and failed at Authority Servers
Is the Web Interface in the 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.

Why is WI installed on the XenApp servers?
The Citrix servers should not have WI installed on them.
Where is CSG pointing to for WI?

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.
There is no need for WI on the XenApp servers and could present a security risk.

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..

I agree since XenApp 6.5 and WI and CSG are all out of support.

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.

With your recommendations I set it up like this:
DMZ:
Server 1: CSG and WI
LAN:
Server 2: XenApp
Server 3: XenApp
I had to update some access rules on firewall to allow for communications from DMZ to LAN.

I would recommend setting up another CSG/WI server in the DMZ to eliminate the single point of failure.
You could use either a hardware device or NLB to load-balance the two.

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.
