Hi,

I am trying to connect to a Mullvad Wireguard Host with my Fedora Linux 
using nmcli, as soon as I up the connection (nmcli con up Mullvad) 
massive amounts of data are sent through the tunnel (according to wg 
1.4 GiB in the first 20 secs).

Any hints on why this huge amount of data is transfered?

Daniel

Sounds likely to be a routing loop? I'm not sure whether NM sets up
policy routing to avoid this like wg-quick(8) does. I would hope they
do, but it might also be rather lazy and not. Worth looking into, I
suppose. In the interim, wg-quick will probably do the right thing.

This is sending telemetry to Fedora.
