I've been 'subdividing' some growing networks into multi-lan; guest,
management networks etc.
On every occasion I've observed that it has taken considerable time
(perhaps 10 to 20 minutes) after the DHCP server begins issuing new
leases (to hosts moved from the other interface) before they show in the
DHCP lease table. These hosts are successfully being issued IP
addresses in the new range, and their MAC's and IP's show up in the
pfSense ARP table, plus I can see the activity in the DHCP log.
Restarting DHCPD doesn't seem to have an immediate effect. So far, it
seems most correlated with the passage of time.
Naturally all of the hosts in all scenarios were moving from a different
interface on the same router. Some even had static reservations (that
were deleted). These have all been 2.2.6 installations. I may have
the opportunity to re-factor as above on a 2.3 installation later this
month.
Any ideas what's happening here? Am I waiting for ARP expiration or
something? Any way to speed up this process?
