Re: At my wits end with waproamd

I'm no expert on waproamd, but I've got it working (sort of):

and hotplug is not instructed to start ath0, and the
/etc/network/interfaces stanza has no "auto" line for ath0 or at
least looks like this (substituting ath0 for wlan0, of course),
complete with "#" before the auto line?

    #auto wlan0
     iface wlan0 inet dhcp

and /etc/defaults/waproamd.conf resembles this?
    ...
    INTERFACES="wlan0"
    HOTPLUG_INTERFACES=""
    ARGS="-e -w -M --scan-interval=3000 --poll-interval=3000 -U"

I'm no help with pump, since I use dhcp3.

Might be easier to set up iptables with separate lines for all the
interfaces you ever use?  There's probably a more elegant way to do
it, of course.  But here's an excerpt from /etc/init.d/myiptables.rules:

	   /sbin/iptables -A INPUT -i ! eth0 -m state --state NEW -j ACCEPT 
	   /sbin/iptables -A INPUT -i ! wlan0 -m state --state NEW -j ACCEPT 
	   /sbin/iptables -A INPUT -i ! eth1 -m state --state NEW -j ACCEPT 
	   /sbin/iptables -A INPUT -i ! br0 -m state --state NEW -j ACCEPT 

The br0 line is for a bridge that links eth0 (ethernet) and wlan0
(wireless) so that the laptop is connected if either one works.  See
the Enabling Ethernet Bridging section of

I repeat, I'm no expert.  But maybe this will help, if only in
provoking someone who understands better to write back and help us both?
