Static assigned IPv6 addresses



  • Having a bit of a glitch getting a new client system to pick up a statically assigned IPv6 address from pfSense. I got it connected and it picked up an address from the dynamic pool. That let me get the DUID of the client and define a static address. Now I want the client to forget the initial address it got and pick up the defined address but I can't get it to let go of that first address.

    I even changed the pool to a new range and restarting the client doesn't pickup the static assigned address. The client is an Odroid H2 running CentOS 7.6. pfSense is up to date on 2.4.4-RELEASE-p2.

    Is there a way to delete the lease from pfSense? I've tried using the trash can icon in "Status -> DHCPv6 Leases" but it doesn't seem to help, and at times it's not even there.

    Android does not support DHCP6. Only SLAAC. (Oh. CentOS duh.)

    You'll need to force the client to release the address. I'm not sure on CentOS, but probably something like dhclient -r eth0 where eth0 is whatever your NIC actually is there.
