Need Help with IPv6 on Time Warner Cable

BryonAdams

I'm trying to configure IPv6 on Sophos XG connected to a bridged modem. I'm thinking I may have to configure additional settings or may have something misconfigured, but it doesn't look like I'm getting an IPv6 lease from Time Warner. My laptop plugged right into the modem and everything rebooted, I get a link local (begins with fe80:) on my laptop. This would mean Time Warner isn't actually providing me a DHCP lease, correct? If that's the case, I'm guessing that the WAN port won't autoconfigure a similar address.

 

Thanks,

  Bryon

    Howdy,

    TWC uses DHCPv6 Prefix Delegation to assign customers IPv6 prefixes. As of SFOS 16.05.0, DHCPv6 Prefix Delegation still isn't supported.

    Thanks Chris! I recently learned from Time Warner's tier 3 that there is conflicting information on their site regarding IPv6 availability anyway, in that it may or may not work for many residential areas. I had installed pfSense to see if it resolved it but I don't always get an IPv6 lease when my firewall asks for it. I think I might do a fresh install of Sophos XG anyway to try and resolve a different trouble where the interfaces would only come up at 10 full when set to auto auto. I'll make a different post for that if I still have problems.
