The best FREE service for this purpose is LogMeIn - http://logmein.com

Optionally, if you want the harder way, you should use a ssh tunnel back to
Linux box in the Internet (at home, university, ...). the dynamic IP
addresses issue can be solved by http://www.dyndns.org or noip.com ...

ssh -R 3389:localhost:3389 <my_linux_box> (it will create a tunnel from TCP
port 3389 of your Linux box to the port 3389 (RDP) of your Windows box. For
SSH on Windows try Cygwin or PuTTY, you can do this even through proxy
servers (suggestion: run your sshd on port 443)

One think I do, is went IPv6. If you have a IPv6 internet connection (or
get a free connection via freenet6.org project) you just connection to
your machine.

You can create IPv6-IPv4 NAT Traversing and now your home machine has a
routed IPv6 address!
