I have that older PC working as gateway (ClarkConnect 2.1).
to get DCC chat and ftp service working i forwarded 2 port ranges to my w2k comp.
so they are not all the time in use...
is it possible to detect these ranges from the inet ?
may be with nmap , but wich parameters?
could this be a security problem, how can i defend?
what about forwarded ports to machines with the cable unplugged?
