1) What command do I use to change the firewall's password?
2) What command do I use to clear ARP cache? We frequently experience problems with a rendom number of users not being able to get out to the Internet (they can see/ping the inside port of the firewall, but that's it). At the same time, other users are able to get out just fine. In the past, we've cycled the power on the PIX and the problem went away.
3) Does anyone know what might be cause problem 2?
Yes it is show nat (also show config will show everything and you can pick your way through looking for what you want if you ever can't remember the command). Show nat should have a range of IPs (that is allowed to be NATed) or 0 0 (allows all IPs).
If you go over the number of users allowed then the subsequent users will not go out. Reloading the pix will solve this until you reach the user limit again. There are timers
Just a thought. If not no worries.
gfullage said this in the "PIX 501-10 and PIX 501-50" question.
"sho local-host" and "clear local-host" are the commands you want to get familiar with. If a host has no connections associated with it then it shouldn't be included in the 10 hosts that your licence is limiting you to.
