Using XTERM in a NAT environment

By net-tekkie ·
I have a situation which I need help on--we are trying to access our network remotely with an XTERM application (Xsoftware) using Checkpoint SecureRemote (newest version). It goes through all the connection steps but never opens the wingdow. Another symptom--if you open a telnet session on the unix host, you can't ping the SR client which established the connection. This used to work when we had all public addresses. Now the servers on the inside network have NAT addresses. The clients are using the private address to access the server.

Using XTERM in a NAT environment

Try this to resolve your ping problem.

On the client side in userc.set, change icmpcryptver from 1 to 0.

Also remember if your machines IP address is in the encryption domain it will not work.

I believe the Unix server MUST have it's default gateway set to the firewall if it doesn't.

Check the IP addresses used by secure remote in the Unix routing table, add a route if it doesn't exist to the firewall.

LAst resort of course is to turn up logging for secure remote connections and watch where the packets are being denied.

Check www.phoneboy.com for more secure remote troubleshooting.
