with many routers, you can't.

some routers have an option to enable remote administration, however  
of those which have this option, every one of them turns it off by  
default.

the reason for this is that allowing remote administration of your  
router is, to put it bluntly, almost always a very bad idea. if you  
allow remote administration of the router, and a "bad guy" knows about  
a bug in the router's web interface (say, a buffer overflow, or a  
default password) then you've just given that "bad guy" full access to  
any machine on your network.

what i normally do is have a linux machine inside the firewall, with a  
tunnel allowing SSH to come through the firewall to that machine...  
and then i use SSH port forwarding to access anything inside the  
network, including the router itself if need be... as long as you're  
careful and the changes you're making on the router don't end up  
rebooting the router, it can work- i've done it before.
