Multiple NAT External to single internal IP via PAT

L0 Member

i have two external IP addresses listening on port 22.  NAT rule does a Port translation for this.

External IP1:22 -> Internal IP141:2222 (PAT from port 22 to 2222)

External IP2:22 -> Internal IP141:2223 (PAT from port 22 to 2223)

 

Traffic to/from external IP1 on port 22 work fine... but traffic to/from external ip2 do not.

 

Is this something that can't be done?

Under the traffic monitor, we do see traffic inbound for the 1st external IP with no issues, and it matches the right security profile.

Traffic for the second IP would show up inbound, but no return traffic.

 

ANd then i just double checked the security policy....  IP2 did not have correct destination zone. (was untrusted, changed to trusted) and it now works.

@JamesFowler,

 

What are you seeing under traffic logs? Is it matching correct security policy and NAT ?

You can check it using test command through cli.
