The problem is that , i have a proxy/firewall box that
provides internet to my internal users, now i have
only permitted the common ports like
ftp,http,smtp,pop3 etc etc & blocked all other , now
there are couple of p2p applications out there that
tunnel through my port 80 as its open, this is taking
up my internet bandwith, i want to stop that ...
regards
