I would like to NAT 3 public ip addresses to one inside ip address and same destination port.
What I mean is.... say for example I have the following 3 public ip address 85.x.x.1, 85.x.x.2 & 85.x.x.3.... so whenever anybody from internet trys to access 85.x.x.1-3 on say tcp port number 25 it should get translated to the one single inside ip 10.x.x.10 tcp port 25....
Hope my requirement is clear...
How to acheive this ?? anybody suggest me on this pls...
This should be simple enough. Do you want to send ports to different internal servers? or a simple one to one nat?
if you want a simple one to one nat, just click on the NAT tab on the configuration screen, and create a nat from the Private IP to the Public or External IP. You should be able to make as many as you want.
If you want to route say port 25 to a different server, and have say port 80 go to a different server, the process is simular, however use the PAT "Port Address Translation" checkbox.
I'm running the same limitation, where my customer has only one SPAM/Relay, wich is the Barracuda that serves two different domains, so each domain has a unique MX, lets say IP "18.104.22.168" for domain "A.COM" and IP "22.214.171.124" for domain "B.COM".
