24.1 Production Series / KEA dhcpv4 arp scan?
« on: March 16, 2024, 04:54:13 pm »
Heya!
Is the new KEA DHCPv4 ARP scanning the network to check if the ip is already in use?
If yes, is the firewall ARP table the same as the KEA ARP table?
Because I've got some IP collisions in my network that could've been easily avoided if KEA would ARP scan the network.
I've got one client who gets constantly offered an IP that's already in use and I can see it in the ARP table of the interface. Meaning I can see the MAC, IP, leasetime etc on the KEA DHCP but if i check the AR{ table of the interface, the IP is already occupied with another MAC on the same switch but a different port
I was switching from ISC to KEA hoping that KEA would ARP scan (as stated in their documentation) and just check that some static IPs are in place and would just avoid them but apparently it doesn't.
Cheers & Thanks in advance
