Help with Multiple Public IPs

So I have 5 public IPs all added to my external nic. I have one that goes into my internal LAN and I want the other four to go to my DMZ. Now my question is how can I link each public IP to a local IP on the DMZ? Also how does astaro know which public IP to respond with? For example if I have IPs ***.***.***.100 - 104 and someone access my webserver on 104 how does astaro know to respond using the 104 address? or does it even matter?

Thanks

Hi, you can setup "additional IP addresses" as new external 'interfaces' (maybe you did that already?).

Then, SNAT the incoming traffic and create PacketFilter rules to allow the traffic to the internal servers.

In addition to Barry's response, another option is to implement a full NAT.

Barry, didn't you mis-type when you wrote SNAT instead of DNAT?

Bruce, what in the question did you notice that made you think of full NAT?

Thanks - Bob

D'oh... yes, should have been DNAT.
(with an optional SNAT for the outgoing traffic, if desired).

Not sure Full NAT would work here.
