Hi all, I'm playing around with Nfuse as if I can get it to work it will solve all of our remote access problems. We have a back to back DMZ using MS ISA server on both sides. Both firewalls are doing NAT. Nfuse is installed on an IIS box in the DMZ. If I access Nfuse (using its external IP address) from a client which is on the internal network all is happy & it works perfectly. If I access Nfuse from within the DMZ or the internet, I am able to log in and see the list of published apps (so I assume XML communication is working) but when I try to launch an application nothing happens. The web ICA client is installed on the box I'm accessing from. Am I correct in thinking that when I launch an app the client is talking directly with the metaframe box using TCP 1494. I can telnet into the metaframe box from the client on port 1494 & see the ICA banner. Do any other ports need opening? Any help appreciated Oh and it's Nfuse 1.7 & Metaframe XPa FR2, IIS 5, Win2k SP3. The only other thing installed on the web server is Progress webspeed. _________________________ Stuart Pittwood, CCNA, MCSE IT Technician Amery-Parkes Solicitors ******************************************************** This Week's Sponsor - Appsense Technologies New!
