I am trying to use the PIX strictly as a firewall (no NAT). However, when I attempt to add an inside ip address to ethernet 1 (for example 12.x.x.65 255.255.255.192) it errors out with "Interface inside ip address or netmask not valid". I've got the outside interface with say 220.127.116.11/28 and DMZ with 18.104.22.168/28 and Ethernet3 hosts with 12.x.x.129/25 without any errors. Any ideas?
Pix 7.1(2), PIX 515E
Interestingly enough, I rebooted the PIX and was still unable to add the ip address. I added another IP address to the interface and was then able to change it to the above address without an error. Just in case anyone else runs into this.
