A customer is requesting this functionality.
Is there a way to access a local server using a public (external) IP address?
This internal server can be accessed from external IPs but when trying to access it from the same local network using the external IP then it is not working.

This can be referred to as Loopback or NAT Reflection in other solutions.

Thanks in advance for any help.
Regards,
Reinaldo

How are your traffic rules defined? I've got the same situation working without any problems...

I've defined a rule which does some destination NAT to my internal webserver IP, the Source is set to ANY and Destination is Firewall and an IP Address group containing my external IP (the last is probably unnecessary) .

When I internally browse to a webaddress which (internally) resolves to the outside IP, Kerio forwards it to the internal system...

HI Dukeman,

Thanks for your help. I have all the NATs/MAPs in place but it does not work.
But after test different options (we have 2 different Internet links in load balance mode) we found a way and for those interested in this topic this is what works for us:
Simply crete a rule as:
Source: Any (or Local Network)
Destination: the_external_known_name (i.e., example.com)
Services: HTTP/HTTPS (choose the service you need) - You can create as many rules as the number of internal servers is
IP: Any (or choose the one you need v4 or v6)
Action: Enabled
Translation: choose Destination NAT, fill in the internal IP and define the port (if it is different from the external port used)
APPLY!
Be safe!
Reinaldo
