I don't think that using a dynamic address is a good thing (because of
the delay between your ip changes and the time you register it with
dyndns for example) ...
But if you use a vpn tunnel between the two machines (with openvpn)
you'll be able to always specify a static ip address (on your remote lan
and not your wan) as destination .
Openvpn has interesting features like persist-tun to be sure that even
if the computer has a dynamic address the tunnel will be restablished
automagically ...
