Hi,
i have a ATP500 (V5.32(ABFU.0) / 2022-10-04 01:59:13) and I've been facing an issue that the ATP does not follow the correct DNS order inside its DNS section.
I have a default trunk at ge2 and a PPPoE at ge3, both interfaces online.
when I nslookup the ATP, it directs the request to the "DEFAULT" at ge3_ppp.
Shouldn't it go through 1...2....3...4 and than - ?
What could be wrong?

Its a problem that I have seen that the first DNS will fire away requests then makes a ICMP port unreachable causing it to skip to the next forwarder.
Something not right with DNS? Destination unreachable — Zyxel Community
