The DHCP WAN address could be problematic. I've got a static IPv4. ifconfig_gif0="tunnel <your-IPv4-here> 12.83.49.81" ifconfig_gif0_ipv6="inet6 <magic stuff> 2602:300:c533:1510:: prefixlen 128 mtu 1472" ipv6_defaultrouter="2602:300:c533:1510::" where <magic stuff> is: AT&T 6rd prefix of 2602:300::/28 + our public IP4 in hex * 16 (i.e. add hex '0') See: https://forums.att.com/t5/AT-T-Internet-Features/Advanced-HOWTO-AT-amp-T-quot-native-quot-IP6-with-full-60-subnet/td-p/4050282
