i have a pair of firewalls running peer to peer HA.
When i try to modify the ip address of 1 of the interfaces to a certain ip address , it gives me a "ifconfig:ioctl (SIOCAIFADDR) file exists" error when i try to save the changes.
i tried changing the interface, creating a new interface with the new ip but it still wouldnt save.
i tried changing that interface with another ip and it was able to work!
can someone advise what is the problem and how to go about solving it?
This error indicates you have a route that overlaps with the IP/mask you are trying to add on that interface. Look at your routes ('cf static q' or 'netstat -nr' on the CLI or in the Static Routing section of the GUI) and see if you can determine which route it is.
