I couldn't reproduce it on my test environment.

- Does it happen every time LAN link is lost?
- Is there any useful information on logs?
- Are you using recent snapshot?
- Could you share <dhcpd> and <interfaces> sections of config.xml?

BTW, the fix applied on 2.0 is still present on 2.1.

- it happens every time The switch connected to the LAN interface gets disconnected, ARP entries disappear and all LAN client fail to connect/ping pfsense and gain internet.

- nothing in logs, just arp entries get wiped out.

-Version: 2.1-BETA1 (amd64) built on Mon Apr 8 03:05:15 EDT 2013

The only fix I found for this is to login to pfsense through WAN and restart the DHCPD service.

meant to say they fail to gain access after the switch is turned back on.

Are there messages containing the strings 'hotplug' (ignorecase) at /var/log/system.log after switch is turned back on?
