Simple recipe for using native ipv6 on an OpenBSD router from Comcast. Tested in Washington, DC.

This recipe does not include any pf modifications you may need to make for your ruleset.

• Install wide-dhcpv6:

sudo pkg_add -rv ftp://ftp.openbsd.org/pub/OpenBSD/`uname -r`/packages/`uname -p`/wide-dhcpv6

• Load up the configuration files/snippets included within this repository, replacing EXTIF and INTIF with the appropriate real interface names. You can duplicate the INTIF sections/snippets if you have multiple internal subnets you wish to route/provide ipv6 for.

• Save local gateway:

netstat -rn | awk '/default/ && /:/ { print $2}' | sudo tee -a /etc/mygate

• Reboot

sudo shutdown -r now
