Yes, if the device supports more then one ip address on the interface.

for example on a cisco router:

ip address 23.43.23.1 255.255.255.0
ip address 23.43.23.2 255.255.255.0 secondary

If you are running version 7.x of software then the unit would not support multiple IP addresses; if you are running version 8.x or higher then yes the device supports multiple public IP addresses [1-1 NAT].

The difference is old or generation 1 X Edge units (as I call them) only can be upgraded upto 7.x version of software and they only support 1 public IP.
The latest or X Edge-e series products can be upgraded to latest 10.x version and they support 1-1 NAT.

Thank you.

I there, i can see the box now for secondary IP addresses.

But that looks to me like it essentially opens the machine up to the elements.

I would like to be able to point an external IP to my webserver for example, and only open ports 80 and 21.

Am i missing a trick here

 

by: dpk_walPosted on 2009-06-09 at 23:14:29ID: 24588367

Secondary IP address as I understand is only available under Firewall->NAT; if you enable this you would still need to create a policy to allow the traffic to the said server.
Sorry but I am not sure if you and me are looking at the same page so wanted to make sure.

Thank you.

Sorry can you elaborate as to what is [not] working.

Thank you.

Well it now works, but using the new firmware!

 

by: BlazPosted on 2009-10-22 at 14:08:45ID: 25639059

@uklive: did you upgrade from firmware 7.x to version 8.x or higher? If so you followed dpk_wal suggestions and should accept his answer.
