Cannot get Teredo IP address in Xbox One
I can't get Xbox One multi-user to work through Airport..MS says to get a public IP address from our cable provider. Would entering my actual IPv6 address in the AirPort router solve the problem?
There is an option in AirPort Utility. Click on Edit for your basestation and then click on Network and Network Options. The Network Options screen has a checkbox for "Allow Teredo tunnels". I assume you check that and it should work. My son had the same complaint with his Xbox One.
I don't know if there are any security issues/risks if this is enabled.
