Can I have a static bi-directional NAT rule and a PAT rule working together?

L2 Linker

Hi,

 

I currently have a static NAT bi-directional policy, number 6 in the screenshot, that publishes an internal server (LAB-Skype) on Internet using a public IP (LAB-Skype-pub). This works fine.

 

Now I need to add an exception for port 443 for that public IP, which needs to be redirected to port 4443 towards the same internal server.

I tried to create a policy translating the original packet arriving at the public server (LAB-Skype-pub tcp/443) to the internal server (LAB-Skype tcp/4443). this is policy number 5 in the screenshot.

 

Unfortunately, I don't see any hit (0) on the policy. Any idea about what I am doing wrong?

If traffic comes from External zone it is destined to your firewall public IP.

Your firewall public IP is located in External zone.

It means that rule 5 destination zone must be External for this rule to match.
