The drawback of having to apply potential changes to the VPN settings to both the the original and the VPN is acceptable. The result is shown in the screen shot on the right.

It really is simple: just duplicate the VPN connection, disable "Use default gateway on remote network" in the original and enable it in the clone. What a nuisance! A simple yet effective solution

Again, the former route is redundant if "Use default gateway on remote network" is enabled, but Windows creates it anyways. Independent of whether "Use default gateway on remote network" is on or off, you may see two more routes: a route to the remote subnet and a gateway set to the VPN endpoint IP and a so-called "On-Link" route with destination and gateway set to endpoint IP. So there's no real need for that exception route. When the VPN connection is in the process of being established, no such route exists but the connection requests make it to the VPN server anyway (via the client's LAN router). Most likely, that default route was configured via DHCP by the client's LAN router.įor some reason Windows still sets up an exception route to the VPN server's public IP although that is redundant. Whatever default route was setup when the system was initialized will remain active. Windows will not touch the default route. If "Use default gateway on remote network" is disabled. Luckily Windows never creates one route without the other if "Use default gateway on remote network" is enabled. There will be another route with a destination of the VPN server's public IP and the gateway set to the client's LAN router. If you open a command line window and type route print you will see a route with a destination of 0.0.0.0 and the gateway set to the VPN tunnel endpoint (most likely an IP address from the remote subnet, i.e. the PPTP or L2TP traffic is not sent back into the tunnel, creating an infinite loop? Luckily, Windows creates second route that exempts the IP packets going to the VPN server's public IP address from being affected by the default route. If the default gateway affects all traffic to destinations outside the VPN client's local subnet, how come the encrypted packets, i.e. Now you may say: well, if it doesn't have forwarding enabled, how do the packets get from the VPN client to the other boxes on the LAN? The anwswer is that there are alternative, lower-layer forwarding mechanisms other than forwarding at the IP layer: bridging and proxy ARP.Įver had the situation where you dialed into a VPN and suddenly your internet connection went down? Right! The VPN connection probably had "Use default gateway on remote network" enabled but the VPN server didn't forward the client VPN traffic to the internet.

In many cases the VPN server doesn't have IP forwarding enabled, for example when the VPN's sole purpose is to connect you to the remote LAN but not further. the VPN server has to forward it to its final destination.

This means that all traffic will be sent through the tunnel and the other end, i.e. Windows will create a new default route with the VPN endpoint as a gateway. Whether a VPN connection has the "Use default gateway on remote network" option enabled has big impact on how network traffic from your machine is routed.
