systemctl stop systemd-resolved
systemctl disable systemd-resolved

[thaloa]

systemctl stop systemd-resolved
systemctl disable systemd-resolved

doing this, all functions like MS-SSTP, OPEN-VPN, SOFETHER VPN etc. will not be affected?. If affected, just turn it back on and you're done, right?

It works with SoftEther clients. Also...

VPN over ICMP / VPN over DNS functions are designed to comply standard ICMP and DNS
specifications as possible, however it sometimes has a behavior not to fully
comply them. Therefore, few poor-quality routers may be caused a
memory-overflow or something troubles when a lot of ICMP or DNS packets are
passed, and such routers sometimes freezes or reboots. It might affects other
users on the same network. To avoid such risks, append the suffix "/tcp" on
the destination hostname which is specified on the VPN-client side to disable
VPN over ICMP / DNS functions.
