Help with x window

Hi experts.
I have OpenVMS 7.2 running on FreeAXP.
I can successfully forward screens to a local machine using "set display".
However i cannot forward screens to my business machine.
Please note that i can establish telnet connection from business machine.

please help me to figure out what i am doing wrong

Lots of things could be wrong.

X-Windows protocol is insecure, having the X11 port open allows people to eavesdrop on your system, so that port is now almost always firewalled off.

So what you need to do is setup an SSH tunnel from your X-11 display to the machines running the application you want to display.

You probably want to setup your FreeAXP system as a font server to your x-11 server or it is likely that applications may not show text as expected.

Now if your target machine is behind a NAT firewall, where its public IP address is different than its internal address, then due to a bug in the versions of Multinet and also UCX/TCPIP, the ssh forwarding is using the public IP address instead of 127.0.0.1. In that case, after the ssh connection to the node, you have to use the create/display command to setup a port on 127.0.0.1 on the same port as the existing show display command.
