I have Cisco pix 515E (HA) firewall on production setup. Initially setup was done for less number of private hosts, so setup is like:
Inside Interface IP is 10.10.8.0/255.255.255.0 .. Here I can use only 255 hosts
My question is Can I add one more private IP block on pix as virtual interface. What is the complete procedure to solve this issue or any other good suggestion without disturbing production pix configuration (as ACL also defined with 255.255.255.0).
