### OpenVPN Policy Routing Example

Source: https://www.asuswrt-merlin.net/changelog-380

Configure OpenVPN policy rules to route specific traffic through the VPN tunnel or to the ISP. Supports single IPs or CIDR subnets. Optionally block WAN access when the tunnel is down.

```text
You can select client IPs or destination
IPs which you want to route through your VPN tunnel.  You can enter
a single IP (192.168.0.1) or a whole subnet in CIDR format (for 
example 74.125.226.112/30).
You can optionally block WAN access to these as well when the
tunnel goes down.
