1:1 NAT possible? Quick answer / discussion

I'm using a D-Link DFL-800 firewall, but understand that it contains mainly of a Clavister operating system. I have a really hurrying problem that hanged over me for two month. On thursday is the D Day. The first question, before I filling up this topic with hundreds of specifications, does DFL-800 make this type of connection (1:1 NAT) work at all?

Thank's in advanced and for a very quick respons.

Yes the DFL-800 supports 1:1 NAT. NAT configurations are discussed in section 7 of the manual:

Thank's for answer. That was not much of help. I've got an external ip-network that should be used internally in my 192.168.x.x network. But I solved it with the dfl-800 together with a vlan-strategy (because it needed a gateway ip) and a transport that sets the gateway as senders ip instead of the dfl-800 interface.

Sorry you feel that way. Your question was; "The first question, before I filling up this topic with hundreds of specifications, does DFL-800 make this type of connection (1:1 NAT) work at all? "
The answer is yes, the rest was just a bonus :-)
Cheers !

It's fully okay. I don't earn any money or knowledge on following this up any more :-). My ambition was to ask several follow-ups, but I founded the solution before. Because the manual wasn't of much help in this very scenario.

Public IP 1, Internal network
GW Public IP 2
 |
 |
DFL800 ROUTER
 |
Gateway Public IP 3
Public IP 3, internal network

This would NEVER worked without setting up the new VLAN (as public ip 3 gw) with an attached VLAN-Switch (because DFL-800 ports are bridged, they can't be tagged), because this dfl800-router already being used for other applications on a private 192.168.x.x network. Also both DMZ and WAN1&WAN2 being used for other applications :).
