I am rather new to DD-WRT, and I'm not entirely certain how to search for this question, although I did try, so my apologies in-advance if this is answered elsewhere.

I utilize Google Fiber, and because I value my privacy, I configured my network and my pi-hole around an OpenVPN configuration in DD-WRT. Unfortunately, now I need to access a service that blocks VPN servers as a matter of policy, since they've been attacked through these servers (understandable and fair).

So, I have no problem deploying a second Pi-Hole on a different subnet, but my question is: is it possible to configure something like a second Virtual Access Point on another subnet that bypasses the OpenVPN Service on DD-WRT and raw-dogs right through to my ISP?

My goal is to have my wireless adapter connect to the raw-dogged AP, and for my Ethernet adapter to connect to through OpenVPN, so I can connect to the service that blocks VPN by switching which network adapter is enabled.

Welcome to the forum Smile

When posting always state router model and build number so that we can give optimal support.

See the forum guidelines with helpful pointers about how to research your router, where and what firmware to download, where and how to post and many other helpful tips:

DDWRT has Policy Based routing both for OpenVPN and WireGuard so you can route according to sources e.g. one LAN client is going trough the VPN and another not, route per destination (routing to my bank is not going through the VPN) but also routing per interface, e.g. your regular wireless is going through the VPN and a VAP (Virtual Wireless Access Point) you created is routed via the WAN etc.

Endless possibilities Smile

The OpenVPN Client setup guide has a chapter dedicated to that:
