Running Two Citrix Farms - How will external access work?

Easy question for all the pros: I have always had 1 citrix server that gave access to users via PN ica clients. I recently configured a second server, in a new farm, and setup web interface. The WI uses Translated secure access with NAT on the firewall.  From WI i can access applications from the original citrix server but I can only acces applications from the new server when I am inside of our network. The ICA file has the server address as my internal address instead of my public IP. Im guessing this is because I need to setup the new server's NAT on my firewall? But I cannot do so because my original server is already configured for port 1494. How do I do this? Does the new server need to be setup to use a different port number?

Port 1604??????????  What old version of the product are you using?

The way I always do multiple farms (same versions, different versions - it doesn't matter) is to have one Web Interface server that is a seprate server from any of the farms.  To me, it is best if it is not a domain member or member of any farm.

Preferably, I use Citrix Secure Gateway but you could use AltAddr.  Using CSG only requires one public IP address. Using AltAddr requires a public IP for each MF/PS/XA server.

In the Web Interface site, you go to Manage Farms and create an entry for each farm.  The farm name you enter there has no bearing on the real farm name.  For each farm entry you create, you enter the name or IP address of the Zone Data Collector(s).

When a user logs in to the web interface, the XML broker service is contacted in each farm you have setup for the web interface site and authenticates the user.  If authentication is successful, the ZDC is contacted to get a list of the apps in each farm the user has access to run.  Web Interface then builds a custom interface for each user showing the apps and or desktops.

When the user clicks an icon, the ZDC for the farm that hosts the app or desktop is contacted to get the least busy server and the user is directed to the server.  (that changes if you are running PS4.5/XA5 and have HRP3 or higher installed)  The launch.ica file is built with the info for the server, the launch.ica file is sent to the client and the ICA client then handles the launch.ica file, goes to the IP address in the ICA file and attempts to launch the app/desktop.

(haha @ 1604. I had to quickly edit that.) OK, I thought there was a citrix product that would help me. I wasnt sure if it was SG or Access Gateway, or something else. Just so I know, CSG is needed to do this? Or is it option 1 or 3?  I'm not looking for any crazy workarounds, just the easiest and best solution.

Thanks for the quick reply.

Safest and cheapest solution is to use CSG.  CSG is free, WI is free and you can get an SSL cert for cheap.

Look at these:

Use one WI server and it will aggregate multiple farms.  It starts to bog down at 5 farms but two is very simple to do.
