IPv6 Teredo Blocking

Hi,

 

I have some IPv6 Teredo traffic

 

I not sure what would be using it since our win 2019 servers are IPv4 only and Pc ip v4 our isp is only ipv4.

 

Can you you block this type of traffic?

I thought I'd take a block and see what breaks approach. 

Turned on content filter Proxy and Anonymizers.

 

Only thing I could think of would be Microsoft update? Updating from another windows computer?

 

 

EDIT :Looking at the current state of Meraki's ipv6 

 

I did the following on the computers

 

Open Run
Type ncpa.cpl
Double tap on the Active Network. A new tab will open.
Click Properties
Uncheck IPv6
Apply > OK

 

No more IPv6. Happy days

 

EDIT2: Apparently setting the registry to disable ipv6 is the recommended approach.

 

 

It would be nice to hear any opinions on why you should leave this on or off? Or point me to an article.

Kind of a big deal

Server 2019 will use IPv6 native and tunnel if it can't get there.

 

Disable IPv6 on your server to solve the problem.
