I am currently running a PIX 515e software version 7.1(1). I am currently using a 255.255.255.192 subnet for my public addresses for static NAT. I am running out of addresses and would like to add another block of IPs from my ISP. If they are unable to give me addresses from the same class c, can I use a different subnet range as well?
ie. - If I am currently running 220.127.116.11 255.255.255.192, can I also add 18.104.22.168 255.255.255.192 or some other subnet on the PIX at the same time? These addresses would be used for one to one static translations for servers and such.
