Re: how to get ipv6 working

Thank you for replying,

You're correct, this is a basic home network. I do not have IPV6 connectivity outside the house as my ISP does not provide it.

I eventually found I needed to append "%trunk0" to the IPV6 address when using it as an argument to say ssh.

Thanks,
John
