@Yury-Pozianos I wanted to configure IPv6 on my omega2+ - after fruitless searches on the interwebs, I decided to put into practice what I learned when making a dumb AP in openwrt. I'd say it was a case of trial and error, except there was no error, nailed it first go First, you'll want to set up a interface to use dhcpv6 with: uci set network.wwan6="interface" uci set network.wwan6.proto="dhcpv6" uci set network.wwan6.ifname="@wwan" uci set network.wwan6.reqprefix="no" uci commit network then run the following: uci show firewall | grep network and take note of the zone that contains wwan my output had: firewall.@zone[1].network='wwan' So, using zone[1]: uci -q delete firewall.@zone[1].network uci add_list firewall.@zone[1].network="wwan" uci add_list firewall.@zone[1].network="wwan6" uci commit firewall and finally service network restart service firewall restart You should now have a fully functional ipv6 client
