Use back to my mac service without a upnp compatible router

Hi, i have a mobile me subscription and i'm interested in using the back to my mac service. Apple says that a upnp enabled router is required, but i don't have one, and because i use IPtv i can't change the router for another with upnp. Anyone knows any form to use this service? Maybe forwarding manually some ports? If it is the solution, what ports I have to fordward? thanks!

PS: my computer is conected to a time capsule router that is conected to my isp router in bridge mode.

all upnp does is open the ports for you.. if you cant do upnp, do it manually:

for that service you'll need to forward ports:
tcp 443
udp 4500

here's a complete list of other mac services and ports they use:

i dont know anything about macs, but i know a thing or two about networking... i have far too many points in the mac category lol

upnp will probably say an error because your router doesn't support it... but, open the ports and it'll work

Ok, here is attached, i think there are working, so i can conect to my ftp server in the ports 15000 - 15001, but no to the back to my mac service.

well those are correct - assuming the machine you want is 192.168.1.222

so next questions... this router... sometimes it's not enough to just forward the ports, sometimes you have to specifically enable those ports inside a firewall, on a different tab in the router... does yours have anything like this in there?

Hi, sorry for the delay,

I don't have any firewall, and I can connect with a VNC client to see my desktop, so the port is not blocked, but i want to use the back to my mac service.
