making FreeBSD phone home via SSH

[Elliot Finley]

Hello all,

I have an interesting project.  I have several FreeBSD servers that I
will be deploying to remote locations.  They will be sitting behind a
NAT.  I would like them to make a SSH connection to a local server
sitting on a public IP.  I need them connected in a way that will give
me remote shell access.

Has anyone done this before?  I'd rather not re-invent the wheel.

TIA for any pointers.

Elliot
