I use wireless networking 'g' and have wireless internet acess via a wireless card modem plugged into the router; just noticed port80 appears open... whats a good way to shield this port filter it i.e... any suggestions apart from installing a firewall which i don't coz most of it is really taken care of by the ISP so they say and the net gear router MBR814X ( dunno if thats got a Nat ) but the interface does have firewall rules and I've set those to accept just the 4 mac ids .... thinking that should be sufficient ...

any other way of securing Port80 ??

Suggestions and advice would be highly appreciated
