I have a PIX 506e Ver 6.3(5) i have an access list access-list NET permit tcp 192.168.2.0 255.255.255.0 host 192.168.77.10 eq 80 static (inside,outside) tcp 192.168.77.4 80 access-list NET but i get a ERROR: invalid netmask 255.255.255.0 with global ip address 192.168.77.4 What is the problem? This is my setup router (192.168.77.1) --------> (192.168.77.3) PIX 506e ---> 192.168.2.x | | | | | | | | | | | | \/ \/ \/ \/ VLAN (inc 192.168.77.x) Any heLp? Thanks
