I just started working for a different company. They have redundant pix525 firewalls connected via serial.
They have decided to change internet carriers due to the divide between Verizon and Level 3. Because of the divide they would have lost their current public ip subnet and found cheaper service through a company called global crossing which means they are also changing ip addresses.
Here is the question: I believe I know the answer already but I just wanted to check and make sure I am not wrong.
Do I need to change the config on both pix's to reflect the public IP address change?
