What I mean...

Your LAN has a 'facade' that it shows the outside world in the form of
a fixed IP address (128.100.165.33 for e.g.). The DHCP server (also a
router) in turn serves up a dynamic IP (192.168.0.100 for e.g.) to a
client computer and routes traffic to-and-from the client on its LAN,
but only traffic initiated by the the client. By default TCP/IP
traffic that is initiated outside of the router will NOT get sent to
any client of the router... so, in that situation you have to tell the
router what traffic to forward and to what computer (I have my router
set to forward most ports I want to use (HTTP, SSH) to my server and
some others to my main computer).
