I have a question about PIX ACL. I found that there are only host objects and network objects in PIX. Therefore, if I have ten machines such as 10.1.0.1, 10.1.0.3, 10.1.0.5,...... 10.1.0.19 and each of them needs to access 100 subnets such as 10.0.1.0/24, 10.0.3.0/24, 10.0.5.0/24, ..... 10.0.199.0/24 with ten protocols such as smtp, snmp, pop3, telnet, ssh, ftp, http, https, dns, imap, do I have to make 10 x 100 x 10 = 10000 access-lists? For Checkpoint FW-1, if I group the ten machines into a group object and group the 100 subnets as another group object and group the 10 services as a group service, then I just need one rule for this. I've tried the PIX Device Manager and search thoroughly on CCO but can't find any example that can reduce the complexity of the ruleset, could you give me some hints how people configuring PIX to reduce the number of rules? Thank you very much.
