Destination Name not resolving to Node Name

[soundsfuzzy]

Hello

Need some help, currently in SmartView Tracker the destination name is not being resolved to the node name (Host Name) in checkpoint.

The case is i am looking at traffic coming into the firewall to our mailserver which has a static NAT address. The destination shows up as a IP address plus a bit of a host name (which happens to be our ISP), i do have resolve IP enabled. I can tell it is to our mailserver as it does include the NAT address in it, but it should show up as the Node Name which is in the firewall?

Does anyone know how to fix this.

The log server (normaly the SmartCenter) or the client PC running SVT (I forget which, but I think its the latter) needs to be able to resolve the IP address to a name.

Are you using an automatic nat rule for the mail server? If so you should still be able to resolve to the object's name.

I am using automatic NAT, for what i am seeing is it is the reverse dns what is showing up because their is a reverse dns PTR record for the IP address. I got the isp to change the reverse entry to see what happened and it showed the changed reverse entry.

So it is not looking in the host nodes for the name? I have looked in the tracker on the firewall itself and on the a remote console as well?

Seems not to be resolving on any of the incoming connection to the node name, but outgoing is fine?

As I recall, it only looks at the objects primary IP, or extra interfaces if added - so it won't pick up the NAT entry.

If this is causing you a real problem, just create an object with the external NAT address. It's not that big a deal.

Another reason I don't really like auto NAt, although this is pretty low down - I don't really rely on the objects all that much, it's easier to use the IP addresses.

Oh and I think Jim is right about it being the client that does the DNS resolution, not the Server.

got the isp to change the reverse lookup ptr, so now they show a bit better.

Thanks for the all the help
