Hi,

to protect your wlan and get access to the internet through IPSec you 
would use 0.0.0.0/0 on m0n0wall side as "Local subnet" and the same as 
"Server subnet" on TauVPN side.

But the problem is that you cannot exclude your LAN subnet from this 
configuration.
Even filtering for traffic to "LAN Subnet" that comes from the IPSec 
tunnel currently does not work with m0n0wall, see 
http://www.m0n0.ch/wall/list/showmsg.php?id=173/07

If you do not need Lan Subnet access I would suggest using WPA and MAC 
filter for securing your WLAN and doing the filtering on m0n0wall like 
you do now on DMZ interface.
