But see, they are not in the same subnet.  They aren't even close. 
The WAN IP address is 120.20.233.182 and the LAN IP address is
120.20.130.161.  The 120.20.130.160/27 subnet is being routed by the
ISP to 120.20.233.182, and so the m0n0 box needs both IP addresses, as
120.20.130.161 will be used as the default gateway for all the boxes
on the 120.20.130.160/27 subnet.  Does that make sense?
