I have a PIX 501 with a single inside network of 192.168.0.1/24. I need to block all IPs above .128 from getting outside.
My question is this -- should I configure two internal networks of 192.168.0.0/25 and 192.168.0.129/25? Or, can I leave the single network of 192.168.0.0/24 and just implement a rule to Deny outbound from inside 192.168.0.129 255.255.255.128 ?
