You need TCP Port 3389 open on any router or firewall the PCs are behind.
Some DSL modems are also routers so you would need to open TCP Port 3389 on
the DSL modem also or place it into a bridge or pass through mode. Check the
documentation for that. If the devices support UPnP then that should, but
not always, open TCP Port 3389. See this article for an explanation of NAT
devices, ie. routers, and UPnP...

You might look at TeamViewer or CrossLoop as alternatives.
