With a host on your NAT router you should be able to access one machine on each network using the public IP address, or name (with dynamic dns if you have dynamic IPs).

At least that's how my Apple NAT routers work.

I pay more for business internet so I can have 5 static public IP addresses. Mainly for a mail server, mail delivery does not like dynamic IP's.

The network admin at work put all the private IP adress ranges on works VPN. So cant use IPs to access other machnines on my own private network. Thank goodness all the Apple compatible stuff uses Bonjour instead of IP addresses. Just leaves my work PC off my local private network cause it can't use IPs unless I turn off the VPN.
