Libreswan on 22.03 not routing traffic through VPN tunnel

On 21.02 I had Libreswan up and running, using the following code in my /etc/config/firewall

        option extra_src '-m policy --dir in --pol none'
        option extra_dest '-m policy --dir out --pol none'

After upgrading to 22.03, the tunnels still connect, however openwrt router doesn't seem to be directing traffic for the remote end through the tunnel, it just tries to route it as normal out the wan. Does anyone have any idea what I could try or any references to any guides that might be helpful?
