Remote Manage Red Hat Enterprise across the Internet

Hi,

I am trying to set up a remote desktop to a Redhat Enterprise server at a clietns site.

At present we have remote desktop going to a Windows 2k machine without any problems, but cannot change this.

I had hoped to use something like LOGMEIN.com to access the RH server but Log Me In does not support this.

Does anyone know of a way that I can set up remote off site access to the RH Server without changing the current port forwarding to the Win2K box?
