first we used my dad's computer as my gateway because it had routing capabilites(it was connected to a hub that split off to my comp and my brothers comp. then the router(i got it for xmas) and the problem with both setups is that people cant connect directly to my computer via ip(they could connect to my dad's tho). i thought there was a way to connect to a lan from the intenet and then connect to a node on that lan but i guess i was wrong. the router is setup as my gateway... im using it to post these messages

just curious... is there ANY way somebody could reach my computer remotely while im behind this router??(would i have to forward all ports to my internal ip or something?)

oh, and what do you guys mean by demilitarized zone? is that just unplugging from the router and pluging straight into my modem?
