While working on a new project I found that a vlan on a firewall had the same IP as an F5 load balancer. This network doesn't have much on it, about 5-6 devices on it, but we are trying to avoid any outage or massive impact. While thinking through this the only thing I can see as an issue is when the gateway IP is changed on the FW the hosts will just need to update there gateway IP. Those devices going down for a few minutes while we switch that over is fine. Otherwise there should not be any other issue, but this is kinda of an odd corner case I have not seen before so I wanted to see if the wisdom of the internet has any other things to bring up.
