Wireguard massive amount data

[Daniel Dumke]

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
