NAT Question

[Piplowe 1]

Hi All, 

A Quick NAT questions.  

My XR300 is in the SKY Router DMZ and the PS5 is in the XR300 DMZ  should the incoming ports not map to the same port ? see below eg. 65530 is going to 59534

Also not sure is this a false positive on the Dos Attack

Are you getting an Open NAT in game? Also do you know what the above logs are from? That might help us understand it better.

The DoS attack message is almost always a false positive, unless your connection is completely dropping at the time of these messages being logged?

Hi Liam, 

Yes I'm getting an open NAT type. 

It's from the logs in the XR300 System information.

OK thanks, I take it you don't recognise that address in the logs then? Either way, this is nothing to worry about!
