I had this little problem, 

 

Network diagram:

 

ADSL Modem "bridge"  <====> WAN PPPoE 196.202.x.x/32 "m0n0wall   

 
LAN 10.10.10.1/16

 
DMZ 196.202.x.x/29

So I cannot ping from 10.10.0.0/16 to 196.202.x.x

And even no internet connectivity on Server holds 196.202.xx.xx/29 connected
directly to DMZ

Now I remember I had similar thing, so I added this on NAT 1:!


Interface

External IP

Internal IP

Description

 


DMZ 

196.202.xx.xx/29 

196.202.xx.x/29 

  

 <https://10.10.10.1/firewall_nat_1to1_edit.php?id=0> edit mapping
<https://10.10.10.1/firewall_nat_1to1.php?act=del&id=0> delete mapping


This should disable NAT on that interface.

Seems to be ok.
