IPV6 Blocked by Firewall

Avast Free Antivirus / Premium Security
1

My ISP, AT&T is implementing IPV6, but the Avast Firewall is preventing the connection to the routing relay.

I would like to make a specific rule to allow 192.88.99.1 to connect to my computer, but when I try to make a rule for it, I’m just taken to my desktop.

I tried Global Exclusions, and that didn’t work. I can allow it to connect by changing the Firewall Policies from Auto Decide to Allow, but I wonder if this is safe, and the right way to go about it?

As you can see below the Firewall is blocking the IP address three to four times a second.

From Wikipedia:

6to4 is an Internet transition mechanism for migrating from IPv4 to IPv6, a system that allows IPv6 packets to be transmitted over an IPv4 network (generally the IPv4 Internet) without the need to configure explicit tunnels. Special relay servers are also in place that allow 6to4 networks to communicate with native IPv6 networks.

6to4 is especially relevant during the initial phases of deployment to full, native IPv6 connectivity, since IPv6 is not required on nodes between the host and the destination. However, it is intended only as a transition mechanism and is not meant to be used permanently.

For anyone interested, here is how to allow a connection blocked by the Avast Firewall.

Click on settings in the Firewall, under Firewall Policies, click on Packet Rules. This is where you can add an IP address and give it a name, and choose to Allow or Block.
