Please provide a screenshot of the Geo-Filter page showing what you see when this happens please.

No need to but you can if you wish

It's better to have a higher ping and a low jitter, puts you more in sync with the server

If the COD servers are being DDOSd, nothing on your router would resolve that for you unless you can find other COD servers in the Geo Filter that are more stable. 

Port Scan Protection prevents anyone from the Internet from scanning the router for open ports to see if any services are vulnerable from outside.
The Spanning Tree Protocol prevents parallel connections in networks with several switches and thus prevents the formation of loops

Port Scan you can enable, it's just a protection option. Spanning Tree you can leave disable unless you have a complex network such as with a lot of switches etc

Hey guys!
in which specific situation can we activate the options:
-Spanning Tree Protocol.
-Port Scan.
any positive impact in connection with this?

Hi Fraser, thank you very much
 

Brilliant thank you, I will let the team know so they can add this.
