yep ... assign 192.168.100.1 to the first one and 192.168.100.2 to the second one also disable DHCP on the second one create a IPSEC VPN between the 2 boxes, and thats it , though on the second box you might need to enable the DHCP forwarder thingy ...
Many Thanks...
Phillip,
What does the IPsec tunnel between m0n0walls buy you? I'm running this exact configuration now minus the IPsec tunnel and everything work fine.
