Split Tunnel issue in VPN

Situation: 1. After establishing a VPN connection, the VPN client canít access the Internet.

2. After establishing a VPN connection, the VPN client canít access other remote resources except the VPN server.

Analysis: by default, the VPN client adds the remote default route to its routing table and increases the metric of the existing default route to ensure that the remote default route is used. The remote default route points to the new connection, which ensures that any packets that are not addressed to the local LAN segment are sent to the remote network. In this case, the VPN client will not be able to access the Internet. Note: click here for example.

However, in other cases, if the VPN client doesnít add the remote default route to its routing table or doesnít increases the metric of the existing default route to ensure that the remote default route is used, the VPN client canít reach the remote resources except the VPN server.

Resolutions: 1. On the VPN server, create a split tunnel to let the VPN client to access the Internet.

2. You can create batch file to delete the default router and another router for the remote network.

3. Refer to this case, Can't access the Internet while using VPN
