External IP address not able to resolve internal webservers

L4 Transporter

Hello,

 

We are unable to open page externally. is there any article to point us on this issue?

 

Using PAN-OS 7.1.10

No recent change/upgrade done.

All router config and NAT checked.

No issue from ISP.

 

Thanks in advance.

Thank you all for the responses. As I mentioned before that the FW was working fine with the NAT setup and suddenly the issue started. We logged a support case and found the traffic was dropped by the zone protection associated with the Internet zone - strict IP address check.

Hi,

 

Are you looking for 1x1 NAT config:

Quite easy to get confused with one to one NAT 🙂

Hello TranceforLife,

 

We are using Source Address Translation. The setup was working fine before. There are quite a few internal Servers and they talk to each other no problem. We can open web URL's internally.

you'll need to add another NAT policy for untrust-untrust as @TranceforLife pointed out , the 'hosting' to 'internet' NAT policy will only take care of connections going out to the internet

 

check out this getting started article and tutorial video : Getting Started: Network Address Translation (NAT)

Hello Farzana,

 

For you to resolve this problema, did you have to disable or strick ip address or some other option?

 

Thank you
