General IPV6 6to4 setting query

[banger]

Using 6to4 IPV6 on my AC1200G+. When first configured the MTU setting is zero but googling suggests 1280. Both seem to work anyone know what the MTU setting should be?

regards

I'd leave it at 0 (the default) unless you have a specific reason not to. The actual MTU could differ depending on your type of connection. The operating system should be able work out the best value to use.
