Dhcp conflicting ips after upgrade #6
Description
Hello team,
I’ve experienced a lot of duplicated ips after migration/upgrade utilizing ISC plugin.
During the upgrade of versions, all the reservations were migrated correctly, but seems opnsense is not respecting all reservations or when conflicts with ARP table ( when ip is granted wrongly keeps giving to ARP table priority instead of reservation)
I tried cleanup tables, reboots and even change reservation IP for the conflicting ones, but reservations seems to not take priority at all.
To solve my issue, i exported all reservations and imported to KEA (default dhcp instead of ISC), disabled ISC and enabled KEA ( subnets/services/etc)
Although I am already ok, opnsense gave me so much over the years, so contributing back.
I submitted all logs via console too.
Replicate issue:
- dhcp isc reservation
- allocate a fix ip (to enforce arp to get wrong ip)
- after that DHCP will start to avoid reservations because take arp priority)
- never getting the correct ip reserved ever(ignoring future ack/ip distribution)
