OX82x / NAS782x architecture overview

History and availability

Known Limitations

The OpenWrt oxnas target doesn't support all hardware features of the SoC.

The Chaos Calmer 15.05 images for the Oxnas targets are missing some essential packages and kernel modules, most notably iptables and the conntrack kernel modules which are required for the firewall to work correctly. If you reconfigure the firewall or network (for example to create a WAN interface), be sure to install the respective packages beforehand.
