I currently use 10.3 and I have a question on ip packet filter.
It thought I knew how tut it fails to filter.
I create access-list 105 as follow
access-list 105 deny udp any any eq netbios-ns
access-list 105 deny tcp any any eq 137
access-list 105 deny tcp any any eq 138
access-list 105 deny tcp any any eq 139
access-list 105 permit ip any any
and I put into etherport say 5 as follow
ip access-list 105 in
then I ping with land host 139, it will kill the machine.
why?
does it suppose to ?
I thought I filter the packet via accesss-list 105.
what did I do wrong?
thnx in adv.
