Yeah you can change it in the webui. Not a big deal really, just change the DHCP server configuration first and then change the interface address, then release/renew on your client. Even if you break DHCP or something you can always statically configure the client to go in and repair the config.
I tried this last night.
And LOORD, the heachaces.
Its something that I've noticed with PF sense for a while now.
Its like if I fiddle around with the WAN/LAN interface options too much - I'm unable to connect to the router.
And even when I restore factory defaults - whatever sub level settings have thrown the system haywire, I cant revert!
The only thing I could do last night, and in the previous instances, was reinstall.
Ever had the like?
