I can ssh to the firewall.  How would I try to ssh to the machine?

You could set up a rule on the firewall to pass SSH data to the server. If the server has SSH enabled you would be able to kickstart the Remote Desktop Client from the command line.

Apple Remote Desktop

Programs written for the Apple operating systems are distinguished from software created for other operating systems in that it must be approved by Apple for use on its devices, whether it is from Apple (Final Cut, iWork, Keynote, Logic Pro and GarageBand are popular titles), or is a third party application from Parallels, Nuance, Microsoft and Amazon, among many others.

Apple Software

Apple devices including Macs, iPhones, iPods and iPad support standard wired and wireless networking technologies, but they also utilize custom applications and some special techniques for networking with each other and with non-Apple devices. Apple manufacturers the AirPort line of wireless networking products, and has its own networking protocols, AppleTalk and AFP (Apple Filing Protocol).
