ssh not responding via VPN (sometimes)

Hi all,
I have a strange network issue.

I have an arch linux box that uses systemd-networkd for managing network stuff.

If I am in the same network, I can access via ssh (however, if I don't type in it for a while it takes some seconds to take the control of the remote shell...it looks like paused).

If I connect via VPN, sometimes I can log in, sometimes the machine does not respond (either to the ping).

From the network infrastructure side, it is all ok, I think it's a machine problem.
Is it possible that the card and/or the daemon and/or the service sets something like a "pause/sleep" period?

Additional information that might be useful:
1) arp -a command takes some minutes for printing the results
2) when I ping the gateway any package is lost

Any idea?

Thank you very much in advance.

Best

NIC specifics? WiFi or wired? lspci? ethtool? iw dev <dev> link?
Does the system go S3 and you WOL it or is it just the NIC?

Re: ssh not responding via VPN (sometimes)

Hi,
it was a wired connection.

I "fixed" the problem by replacing networkd with networkmanager.
Now it works perfectly.
Same card, same cable, same all...I don't know what happened.
It looks like I had some problems with networkd.

Thank you.
