Cisco PIX 520 Configuration

By rbrindisi ·
I am unsure about the global (outside) line below. Our ISP only provided us with 6 external IPs. I have already used 2. Will the nat (inside)be able to provide enough IPs for 15 users?

Thanks

You shouldn't post full setting on internet

Just a reminder. Everybody knows your settings from now.

It doesn't matter how many external IPs you used for NAT. One IP is fine too. Firewall will make mapping between outside and inside. Except you have special needs.
