Opening Ports and Forwarding Ports on The ASA5510
Posted on 2011-10-20
So I am trying to open ports 443, 22 and 25 on the ASA5510. I then want to forward all external traffic coming on ports 22 and 25 to a spam appliance and 443 to my mail server.
I have created the following objects
T1 - External IP
SB - Spam Box
MA - Exchange Box
Mail - TCP port 443
Spam - TCP port 22, 25
I created the following Access rule: I think this opens up 25, 22, and 443 to the outside.
Source ANY, Destination T1, Service: Mail, Spam, Permit
Now I am unsure how to forward these. I am trying with a Public Server Rule
For the public server I am trying to add a rule to forward all 25 and 22 traffic to my spam box:
private interface: Management (basically my internal gateway)
Private Address: SB (spam box object)
Public Interface: T1 (external IP)
Public IP: ? if I put our external IP it says they cannot be the same.
Also, is a public server rule the right way to forward this info?
