After trying a few things that were suggested to me, I realised
what the problem was. Without the DEFAULT_TO_ACCEPT option my
DHCP client couldn't re-lease the IP from my ISP's DHCP servers
and presumably ended up using an invalid IP..
I've added the following firewall rules:
# DHCP
${fwcmd} add pass tcp from any to ${oip} 67 setup
${fwcmd} add pass udp from any to ${oip} 67
${fwcmd} add pass udp from ${oip} 67 to any
${fwcmd} add pass tcp from any to ${oip} 68 setup
${fwcmd} add pass udp from any to ${oip} 68
${fwcmd} add pass udp from ${oip} 68 to any
and removed the line
${fwcmd} add deny all from 0.0.0.0/8 to any via ${oif}
which seems to have worked thus far.
Cheers,
