      Hi all,

      I'm using an OpenVPN connection where all trafic is routed through (disabled the LAN to WAN NAT, only LAN to VPN is enabled) but I noticed in the stats that the (outbound only) traffic on then WAN interface is almost as double as high than on the VPN interface. How comes? As I disabled NAT on WAN from the LAN side there shouldn't be any LAN traffic going out over WAN, thus I suppose it might have something to do with VPN overhead or else?

        If you are using the WAN address to connect to your VPN , which is almost certainly the case, its going over the WAN and back out….

          so this is a normal behaviour and not any traffic leaking out of the VPN tunnel?

            Have you checked firewall states for your WAN? That'll immediately tell you if there is LAN-WAN traffic.

              You're connecting to the WAN address when using OpenVPN, right?

                Yes and I didn't see anything there, thats why I was curious how that doubling comes. It also checked the real life traffic and selected "remote", so I only saw the VPN destination on WAN and all other remote addresses I connect to in VPN.
