Enabling IPV6

See Also: Official digitalocean ipv6 guide.

First, you'll need to fill in digitalocean's network config template:
(details on droplet page)

# /etc/rc.conf

defaultrouter="${IPV4_DEFAULTROUTER}"
ipv6_defaultrouter="${IPV6_DEFAULTROUTER}"
ipv6_activate_all_interfaces="yes"

ifconfig_vtnet0="inet ${IPV4_ADDR} netmask ${NETMASK}"
ifconfig_vtnet0_ipv6="inet6 ${IPV6_ADDR} prefixlen 64"

If moving packets between network inferfaces, enable gateway for ipv6

# /etc/rc.conf

# if moving packets between ifaces
gateway_enable="YES"
ipv6_gateway_enable="YES"

If you plan to use more than one of the 16 ipv6 addresses, create network interface aliases for them.

# /etc/rc.conf

# create public ipv6 aliases
ifconfig_vtnet0_aliases="\
                      inet6 ${YOUR_DO_IPV6}:f002 prefixlen 64 \
                      inet6 ${YOUR_DO_IPV6}:f003 prefixlen 64 \
                      inet6 ${YOUR_DO_IPV6}:f004 prefixlen 64 \
                      inet6 ${YOUR_DO_IPV6}:f005 prefixlen 64 \
                      inet6 ${YOUR_DO_IPV6}:f006 prefixlen 64 \
                      inet6 ${YOUR_DO_IPV6}:f007 prefixlen 64 \
                      inet6 ${YOUR_DO_IPV6}:f008 prefixlen 64 \
                      inet6 ${YOUR_DO_IPV6}:f009 prefixlen 64 \
                      inet6 ${YOUR_DO_IPV6}:f00a prefixlen 64 \
                      inet6 ${YOUR_DO_IPV6}:f00b prefixlen 64 \
                      inet6 ${YOUR_DO_IPV6}:f00c prefixlen 64 \
                      inet6 ${YOUR_DO_IPV6}:f00d prefixlen 64 \
                      inet6 ${YOUR_DO_IPV6}:f00e prefixlen 64 \
                      inet6 ${YOUR_DO_IPV6}:f00f prefixlen 64"

If hosting regular non vnet jails, you may need to create ipv6 aliases for your jails.

# /etc/rc.conf

# create private ipv4 clone addrs
cloned_interfaces="${cloned_interfaces} lo1"
ifconfig_lo1_aliases="\
                      inet 192.168.32.1/24 \
                      inet 192.168.32.2/24 \
                      inet 192.168.32.3/24 \
                      inet 192.168.32.4/24 \
                      inet 192.168.32.5/24 \
                      inet 192.168.32.6/24 \
                      inet 192.168.32.7/24 \
                      inet 192.168.32.8/24 \
                      inet 192.168.32.9/24 \
                      inet 192.168.32.10/24 \
                      inet 192.168.32.11/24 \
                      inet 192.168.32.12/24 \
                      inet 192.168.32.13/24 \
                      inet 192.168.32.14/24 \
                      inet 192.168.32.15/24"

Make sure your firewall allows expected traffic through ipv6

sudo pfctl -sr  # examine rules

Finally, restart your network and test

# restart networking
sudo service netif restart
sudo /etc/rc.d/routing restart
