Pan OS 4.1, Destination Nat Problems

Retired Member — Fri, 25 Nov 2011 07:04:10 GMT

Hallo,

I installed a PA500 wit Pan OS 4.1 at customer side and most thing working fine.

I configured the WAN interface as DHCP-Client with default route to this interface. In NAT-Rules i want to publish a internal server to give external sources acces to this internal source (simple portforwarding). My problem is, if I configure a destination translation, the PAN OS needs an address in the destination (not destination translation). A commit of a new rule set without a destination address fails. If i take my WAN-address as destination, everything works fine. Problem is that this IP changes from time to time. Is there the possibility to specify the interface or 'any' in this kind of use?

Regards

Robert

You could use an FQDN object with a DYNDNS host.

Hi,

that would be an idea but there is no possibility to configure dyndns options on the device.

You don't need to have dyndns ON the PAN.

You just run a dyndns client behind your firewall to keep your dyndns records up to date . ( I guess you already have this , otherwise how can you host a webserver if you don't have a fixed ip )

In the NAT destination you then just use the dyndns record.

that's it.
