OpenVPN with static key for all local network clients

[Andreas Gohr]

I'm trying to setup my router running the AsusWRT-Merlin firmware as an OpenVPN client. The VPN is a simple static key based one to my root server. The goal is to have all traffic from my local net to be routed through the VPN.

Under VPN -> OpenVPN Client I set up the configuration for connecting to my server using the local/remote endpoints of 192.168.42.2/192.168.42.1 and set Redirect Internet Traffic to All Traffic. The VPN is up and running, but my traffic is not routed through the VPN.

System Log - Routing Table shows the following:

Destination        Gateway          Genmask            Flags    Metric    Ref    Use  Iface
192.168.42.1       *                255.255.255.255    UH       0         0      0    tun11
100.74.255.254     *                255.255.255.255    UH       0         0      0    WAN
192.168.1.0        *                255.255.255.0      U        0         0      0    LAN
100.74.192.0       *                255.255.192.0      U        0         0      0    WAN
default            100.74.255.254   0.0.0.0            UG       0         0      0    WAN

As you can see the VPN TUN interface is up correctly, but all traffic is still routed through 100.74.255.254 which is my current cable modem IP.

Question is how/where to configure that all local network traffic goes through the VPN?

"redirect internet traffic" should be set to "no"

I tried that too, but it changes absolutely nothing. Routes are the same and traffic still does not go through the VPN.

Is it broke? This post will show you how to customize the VPN routing script. Just in case you want to try.
