help start dnsmasq when eth0 times-out? [SOLVED]

Hello, I have a computer configured as a wifi hotspot/router. Eth0 is cable to upstream dhcp server (Comcast/etc). Wlan0 is a usb wifi adapter and the target interface of dnsmasq. Starting dnsmasq necessarily attempts to start eth0 ... I guess for dns-forwarding purposes? ... If eth0 does not obtain an ip (i.e. not plugged in) then dnsmasq fails to start and I cannot connect via Wifi to the router, which is my problem. I need dnsmasq to start even if eth0 fails to get an ip. Thank you for any help!

Hi,

You could try a few things...
- edit /etc/init.d/dnsmasq to depend on net.wlan0 instead of just net
- bridging wlan0 to br0, and and set interface=br0 in /etc/dnsmasq.conf
- rc_depend_strict="NO" in /etc/rc.conf
