the machine in question is offsite. i am going back next week to
attempt to secure it properly.....my friend has no money for a router
so we need to do the job with a software firewall ....as i said we are
well protected here with hardware firewall so i cant do much to test
this .....ip address of his computer is fixed and a previous virus
infection has allowed access to a server that is still attemting to
download virus.....
the only visible port is 135 and that is open....obviously my
knowledge here is deficient as i closed the port to tcp + udp which
did nothing...... my simple question is if i kill the port for icmp
will that cloak it.....i am using kerio pf
thanks again
