IPSec Client - Routing all traffic into VPN tunnel

You can easily route the entire network traffic of your local client into the VPN tunnel with the IPSec VPN Client.
This is helpful for exmaple if the opposite WAN IP should be used for external access instead of the local gateway.

The following two steps describe how to send all traffic into VPN tunnel after the VPN tunnel has established.

1) Change Local Policy to 0.0.0.0 (any)

2) Change Phase 2 Settings:

In the VPN gateway (phase 2) settings, enter 0.0.0.0 as IP Subnet for the Remote LAN address and subnetmask.

3) Disable split tunneling function

To disable the split tunneling function on the IPSec VPN client navigate to

VPN connection > IKEv1 parameters and enable the Disable split tunneling option.

If something goes wrong

Please try to create a policy route for routing the traffic through the VPN
