Probably, but I've never tried it.

Is it possible to set the MSS with TCP and iptables when the network is bridged?

Thanks!

Best Regards

On the gateway host I configured a manual host route of the vm ip via the tunnel.

The strange thing is. If I ping from this vm to 8.8.8.8 it periodically looses traffic. Also incoming traffic is sometimes timing out.
But when i start a background process on the vm that pings the gateway ip. These timeouts disappear.

Do you have an idea, about what can cause this?
