Zeroconf anywhere?

[Themer]

I can access my Zeroconf "share" from any computer on my LAN by typing in the IP and the port number (192.168.etcetc)... I am wondering if there is a way to access it from anywhere by using my "real" IP - the one unique in the world, not just in the LAN. I won't post it for obvious reasons but I happen to know the unique IP for the router... is there one specifically for my computer? I would think so but I don't know how to find it, or even if this is possible...

You need to forward a port on the router in to the PC.

I thought of that, but lets say I enter the path like <IP>:<port>
Yes, that would point it at the PC, but how would it know which port for the share to use? What I'm thinking is this - right now, I can enter this to get to it locally:
<local_IP>:<Zeroconf_port#>
In theory, using the router IP and port number that forwards would be like this:
<router_IP>:<port_for_link_to_comp>
thus obviously needing the "<Zeroconf_port>" part in there somewhere. would it be like this:
<router_IP>:<port_for_link_to_comp>.<Zeroconf_port #>
or something else, or what...
