      Hello,

      I've attached part of my system log below, but to summarize:  It appears that the dhcp client sends renewal requests directly to the last IP that it successfully received a lease from…every minute or so for up to several hours ... before finally doing a DHCPREQUEST broadcast. It further appears that my ISP's dhcp server only responds to DHCPREQUEST broadcasts and not a direct request to it's IP address.

      I'm not sure what the correct behavior should be on either end, but is there a way to configure pfSense to always do a broadcast at renewal vs. attempting to send a request to the IP of the last dhcp server it got a lease from? Alternatively, is there a way to configure the number of direct dhcp renewal requests it should attempt before doing a broadcast? Or is everything "working as designed"?  :)

      Thanks...
