Hi guys as title suggests I have a pi 4b 4gb and basically I want to connect it to my isp provided router (wired connection via a lan cable) and run an openvpn config on it and then connect it to an access point that i already have (this one is wired too via a usb to RJ45 adapter and lan cable). I know that I need to flash openwrt image on an sdcard and install it on pi4 but I don’t know how to configure openwrt after that and honestly the guides on the forums and internet are a little confusing (I’m not that tech savy) also I read that not all usb to RJ45 adapters work with openwrt on pi4 but I don’t know which one to buy. can anyone show me a fool proof guide or tell me what I need to do? Edit: thank you all amazing people for your input I found a Google wifi mesh solution second hand (ac-1304 model) that is supported by OpenWRT latest firmware for a good price and I went with that. Gonna find a proper use case for my Raspberry Pi in the future for now gonna keep it as a tinkering device.

This may be helpful if you haven’t found it yet. It has a full list of instructions to flash and configure openwrt on the rpi 4 with wireguard VPN. It says you can also do it with openvpn, but claim the speed was much slower.

Thanks I haven’t seen this guide before. It looks easy enough to follow
You have the pi, give it a go.
If it’s inadequate then i’d recommend a used fanless thin-client type PC, such as a Wyse 5070, just make sure it comes with PSU and a few GB of RAM and SSD. And check reports of how much power it uses at idle.
Thanks I will try running Wireguard on pi4. I never considered tin-clients before. What kind of OS these have? Can they run VPN clients?
Usually they’re normal x86 PCs with nothing unusual about them so just your Linux/BSD distro of choice. You can look up the processor model to see what crypto acceleration it can do, or see if there’s any wireguard benchmarks available.
Some have interesting processors like PowerPC, or other strange hardware, but avoid them unless interesting is what you’re after.
Sounds interesting I’m looking for a good mikrotik router right now. Going to look for these too thanks
Maybe this one ? https://www.pivpn.io/
Thanks but this is VPN server setup not a client
It sounds like a fun tinker project, but I don’t think the hardware will perform as well as you hope.
Yeah like know open-vpn not gonna run well on it but wireguard is ok
Just install Raspbian and PiVPN and forward the right ports dude; Less complicated
Thanks but I think you misunderstood. I don’t want to run a VPN server I want to run a openVPN client on a router
I miss not being a CGNAT user.
