There are two ways to do this.  First of all, Chris is right; you have 
to forward the port through his router if he's not connected directly 
to his modem (note, some ISPs offer modems with a built-in router; ask 
here and give model numbers if you're not sure).

Next, to keep track of his DHCP-based IP#:

You can either him sign up with one of those DNS-hosting companies that 
host dynamic IP#s; one example (I have no connection with them) is: 
http://www.dyndns.com/services/dns/dyndns/

They're free.  You get some software to install on his system so they'll 
keep track of his whereabouts.

Another way to do it (this is NOT recommended because it only works if 
his system can send email when you want to log in): have him send you 
an email from his system, then look at the headers to determine his 
IP#.

I've used both systems; I prefer the former.
