WAN Interface test fails

Acanter

Hello,

I have a zyxel usg 200 that has a problem, the Nebula-compatible WAN Interface test fails.

What can it cause this problem?

You can have a try to setup DNS Server. (e.g. 8.8.8.8)

HI @Acanter ,

It is DNS resolve issue, after enabling DNS Security option, it is okay now.
