Hi Frans,

do you know if the address provided by the cable-modem is a public one? Some
providers serve with private addresses, which could be a 192.168.-like
address with a /16 subnetmask...

Another cause could be that the modem offers a DHCP lease for the first x
seconds in the 192.168 range, and then offers a new lease with the public
address (after it authenticated/initialized the connection with the ISP)...
This would explain why it works afterwards.

I would try and change the (LAN) address of the m0n0wall to one in the
10.x.x.x range, just to see if it does the same...

Kind Regards,

Subject: [m0n0wall] dnsmasq fails to load on boot

I've just noticed after rebooting my m0n0wall system that dnsmasq fails
to load on reboot. The error given in the system logs is "dnsmasq bind
failed: address already in use". I assume that this is referring to an
IP address conflict rather than a NIC conflict.
The settings on the firewall are:
OPT1 =
DHCP range is - 
I can't see any problems with this setup like overlapping IP ranges and
even if m0n0wall is the only system running on the network, dnsmasq
still fails to load.
Interestingly if I log in to m0n0wall and click the "save" button on the
DNS forwarder page, dnsmasq reloads itself without any problems. Does
anyone know what could be causing this.
P.S. One other thing to note is that I'm using an Ethernet ADSL modem.
The modem IP is but it serves the IP address it receives
from my ISP back to the WAN interface on m0n0wall.
