I have a Pi set up as a OpenVPN router behind my main router for certain VPN only clients. All works nicely.

I'd like to add a wifi adaptor so I can utilise the VPN via either a LAN cable OR Wifi.

The LAN adaptor is the standard bridged config, and runs a dhcp client for VPN clients.

I'm not sure how to configure the Wifi adaptor so it utilises the LAN DHCP server ?

I am thinking that perhaps I run it as Protocol 'unmanaged' and bridge it with the LAN interface?

Any suggestions appreciated.

Just add the AP to the existing LAN bridge.  You do that by specifying "option network lan" in /etc/config/wireless.  You do not need an additional network, there is no need to change /etc/config/network at all.

Thanks... I though that might be the way but wanted to check !
