Nethserver 7.9 - Bandwith Monitor

Hi All,
i have a question about the bandwith monitor that makes me crazy.
In the “Top Local Host” i have an entry like this: 192.168.x.x (My Wan Address)

That keeps always consuming bandwidth, about 2Mbps average.

i Took a look at GUM GUM website, but i do not understand why my wan interface is resolved with that hostname and why is it consuming so much bandwidth.

Can anyone help me?

Thank you.
