Proxy traffic is not routed by OpenVPN tunnel

[TREYKOV]

Good afternoon,

I have enabled the OpenVPN client on my local firewall. All internet traffic is routed to the internet through my OpenVPN Access Server in the cloud. This works correctly.

In my local firewall that works as an OpenVPN client, I have enabled the transparent proxy service with ssl inspection and cache. This is working with the particularity that web browsing traffic is not coming through the OpenVPN tunnel.

All web browsing traffic of the proxy service is coming out through the WAN interface.

How can I force this traffic to be routed via OpenVPN tunnel?

Diagram:
Lan >>> OpenVPN >>> Access Server >>> Internet (It works Ok - No proxy enabled)

What may be missing in my configuration?

Thanks in advance!
