Firewall/NAT

Following setup (Can I use M0n0wall as a true Firewall disabling NAT?)  

M0n0wall 1                                                 M0n0wall 2
LAN -> 10.40.1.1/24
WAN -> WAN Interface                               LAN   -> 10.40.2.0/24
OPT1 ->   --------------------------------->        WAN  -> WAN IP 10.40.1.254 / GW 10.40.1.1  
(Opt1 is bridged with LAN)


Enabled Advanced NAT to disable NAT on M0n0wall 2
Add Network 10.40.2.1/24 as Rule on OPT1 any to any
Add rule on OPT2 (for bridged interface)

nslookup on a client in 10.40.2.0/24 works fine. But any acces to an IP in the LAN on Monowall 1 didn't work. Any access to clients on the external WAN didn't work. Both is blocked on Monowall 1.

M0n0wall release is 1.3 on both (WRAP and ALIX)

Any ideas, hints or suggestions?

In the meantime I also tried some of the other hints which I found on this site. Didn't work?

Is that an issue of release 1.3?

Everything works fine wit NAt enabled. As soon as I enable Advanced NAT on m0n02 it stop working.

Heureka, I got it!  I simply need a static route on m0n0wall one to the respective IP adress of the WAN IP of m0n02.

I would guess it make sense to do some more documentation around this topic? There are some people asking for this.
