If you use a m0n0wall in filtered bridge mode.
Cisco router 188.8.131.52/23
m0n0 bridge (WAN) 184.108.40.206/23 (220.127.116.11 is gateway address)
Clients off OPT interface with 1.2.0.x/23 and 1.2.1.x/23 addresses,
gateway is 18.104.22.168 (22.214.171.124 works also?)
Disclaimer, I have never tried anything like this, but the network
'math' seems correct.
