I'm planning to move a pair of PIX 515E-UR (active/standby pair) from one location to another together with the Internet connection. There are 3 interfaces in used, inside, DMZ and outside. As it turned out, I don't have to change IP addresses on DMZ and outside interfaces but I will have to change inside IP since they're being moved onto a new subnet. Just wanted to hear from your experiences what are the parameters that need to be changed. I should be approaching a consultant for this but just wanted to know what involved. Thanks in advance for you replies.
