Multiple subnets on PIX

Unanswered Question
Apr 2nd, 2007

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 123.123.123.0 255.255.255.192, can I also add 200.200.200.0 255.255.255.192 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.

I have this problem too.

Hi

Yes this will be fine. Your public IP addresses do not need to be contiguous. As long as the ISP routes the new address range to your pix it will work.
