I am not quite sure if I get something wrong or do something wrong. Please
let me explain the test scenario:
I have some Soekris Box with m0n0 on it within such topology:
Upstream/ISP - m0n0 - LAN
The IP ranges are like that:
Upstream - Public IP - m0n0 - NAT / 192.168.100.0/24 - LAN
Which means there are WAN to the ISP, LAN as a private network with NAT
from the inside out and the OPT2 interface as DMZ with public addresses.
Now I want the requests to the DMZ to be routed from the WAN to the DMZ by
m0n0. The LAN interface should be nated only from the inside out.
I also added some rule to the firewall allowing HTTPS from WAN to DMZ
<descr>WAN -> DMZ (HTTPS)</descr>
I also added one rule allowing all traffic from the DMZ to the WAN.
My problem is now, that this does not work. Going from the DMZ->WAN always
is making NAT. Going from the WAN->DMZ does simply not work.
What am I missing? Or is something wrong with the m0n0 fw?
Thanks for your help in advance,
