@jlepthien:
Since all traffic is on WAN interface there is no chance for the shaper to do its work. I suggest you set up a file server to which both clients can connect and then share stuff on this way.
Ok, thanks for the reply. Unfortunatly, such transferts are mainly done with scp, because VPN are used to connect several LAN's, so a file server is not an option.
I will put the openvpn server behind the firewall, by this way all traffic will go from WAN to LAN and from LAN to WAN.
