The factory setting for this router on older firmware is for DNS to be open on the WAN IP as well as the LAN IP. This will be changed when configured by AAISP, but if it is configured from new, or reset, then WAN side DNS may need to be disabled. This can be done from the web interface and '''setting DNS Access Status to LAN'''. Go to:
> Advanced - Remote MGMT - DNS - LAN

sys server access dns 1
