SoftEther VPN Server doing loads of DNS Queries

Post by devedse » Mon Mar 15, 2021 12:12 pm

A short while back I've setup a PI-Hole in my network to block advertisements. This also allowed me to capture any DNS queries.

What I've seen is that my ODroid XU4 running SoftEther VPN server is sending out loads of DNS queries for the keepalive.softether.org domain.

This is said to be detecting DNS hijack.

Can someone elaborate on this (DNS Hijacking) in the context of Softether?
I mean, does running Softether expose me to this attack? And do we need to do constant DNS queries to detect / resolve this? And how does it get resolved if it gets detected?
