I am trying to prepare myself for the SNPA exam, and am stuck on the static command. I understand the basic IP to IP translation version of the command (static (IF/IF) IP MASK IP MASK), but I am lost when I start seeing numbers at the end of that string. The command syntax confuses me because there are so many options. For example, examples provided to me for allowing outside access to a DMZ-based web-server are written static (dmz,outside) Out_IP Out_mask Dmz_IP Dmz_mask 0 0 ... What are the zeroes??? I know that you can specify embryonic connection limits, but that is just one of those numbers..what's the other?
