[pfSense Support] unexpected dhcp lease
Hi, I have a problem with pfSense's dhcp server since 0.85.x (I guess it wasn't an issue in 0.84.6). I have two lan interfaces and both serves as dhcp server, of course not overlapping. My problem is that on lan2 (opt2 - xl0) a dynamic ip address is always issued despite it shouldn't be because only fixed leases expected. This is the only address I have to configure for the dhcp servers range. What's more strange for that mac address (00:12:79:ad:c6:fc) is a fixed lease reserved on the other (fxp0) interface. Which as I see in the logs once offered, but the other address picked up. This never happened on the other interface. In syslog I have: Sep 28 14:35:04 last message repeated 2 times Sep 28 14:35:03 kernel: arp: 192.168.2.254 is on xl0 but got reply from 00:12:79:ad:c6:fc on fxp0 Sep 28 14:34:49 last message repeated 5 times Sep 28 14:34:36 dhcpd: send_packet: Invalid argument and in dhcp logs: Sep 28 14:35:03 dhcpd: DHCPNAK on 192.168.2.254 to 00:12:79:ad:c6:fc via fxp0 Sep 28 14:35:03 dhcpd: DHCPREQUEST for 192.168.2.254 (192.168.2.4) from 00:12:79:ad:c6:fc (TRC-dc5100) via fxp0: wrong network.

Re: [pfSense Support] unexpected dhcp lease
Are these two logical networks on the same physical network? I'm noticing the request came in on both fxp0 and xl0 - that seems kinda odd.

I'm noticing the request came in on both fxp0 and xl0 - that seems kinda odd. Yes, both network cards are connected to the same switch, but I guess as the deny unknown clients option is enabled on both interfaces (static arp as well) this shouldn't happen.
