I have a client needing to access a Citrix server behind an e-smith server and gateway firewall. Citrix provides the following document: Document ID -- CTX953919 Last modified on: Thu Aug 03 12:12:05 2000 The recommended set up for this Web Computing Solution is to have your Web server outside the firewall and have your Citrix servers inside the firewall. Checklist Firewall 1. A valid external IP address has been mapped to the Citrix server inside the firewall. 2. Port 1494 for TCP/IP is opened. 3. Port 1604 for UDP is open Inbound on the firewall. 4. Port 1023 and above are opened for TCP and UDP outbound. <end> To assist replies, let us state the following: external ip = xxx.xxx.xxx.xxx internal ip = yyy.yyy.yyy.yyy How may I best implement the above at the e-smith server? Does anyone have any experience with Citrix and e-smith working in this fashion?
