Hi Ray,
So what you’ll need to do is set up port forwarding and also set up DHCP reservation list on the ES450.
The port forwarding will point to the client pc and port used is TCP port 3389(RDP port).
The set up instructions is on page 143 of the ES450 guide for the port forwarding.
The DHCP reservation is on page 98. It would be better to give the client pc a static ip address, and add it to the list.
So, from the other computer you would RDP to the ip of the GSM modem example 213.x.x.x.
And then do the setup for the other GSM modem. You would always use the pubic ip address since its accessible from the internet.

The other solution is to set up a vpn on both modems, then you can just use the ip’s of the client pc’s.
Hope that clarifies.
Thanks,
J.
