I am receiving a message in the dhcp log “There’s already a DHCP server running.”. I have 2 interfaces ETH0 = WAN and ZS is serving up DHCP just fine but on ETH01 my LAN side there are no replies to DHCP requests.
Sniffing the LAN, there is no other DHCP server running so why am I getting this error?. I am running a plain jane ZS configuration and my alternate ZS running as a virtual server runs dhcp just fine on both interfaces.
I have been poking around on the net for hours, trying all sorts of things. Checking the pid file, conf file etc.
For those who stumble across a similar problem. I finally went and hooked my LAN on my ZS computer directly to my MacPro for testing. Turned off the dhcp server on ZS and turned it back on and it started serving IP to my Mac. Plugged it back into the LAN switch and everything is working. I have no idea what fixed it other than a stale cache somewhere.
BTW, on ZS the DHCP log still says another DHCP server is running but it is handing out IP regardless.
