DMZ Transparent Mode
« on: February 11, 2011, 03:05:34 PM »
Hi everyone, I need to change the DFL-800 configuration, in this way:

WAN1: IP Public (XXX.82.215.94) / Net: XXX.82.215.88/29 / Gateway: XXX.82.215.89
DMZ: (servers with ip public) for example: PBX with two nics: IP PUBLIC: XX.82.215.90 and IP LAN: 10.100.1.6

I don't know how to configure DMZ, to work in transparent mode, because the servers need to connect to internet with IP public, and without NAT.

Any suggestion would be appreciate.

Thxs. ???

what you can do is to configure the dmz interface with same ip settings than the wan1 interface and in the interface/ethernet/dmz tick the enable transparent mode box.
Your servers will have as default gatewy your isp router.

I have tried this. But the server cannot reached to/from the public IP. I fact, from tools/ping inside the FW, I cannot ping to the public ip.

Now, the DMZ have the same IP, same network, and same gateway. And transparent mode in dmz interface.

Maybe I need add some Ip rules.??

you need to do the reverse allow rule from the wan1 to the dmz.

Could you give more details? I have no experience with this brand firewall.

Hi, I have include an images about the actual configuration, maybe could help to see if Im doing something wrong.

Mainroutes:


Ethernet:

And I have connected the PBX Public Nic direcly to DMZ port, and from ping tools inside the firewall I cannot ping to PBX and from PBX cannot reach internet.

Thanks ;-)

Finally, I solved the problem, You need to activate the transparent mode in both DMZ and WAN, and works.  ;D
