turning a raspberry pi 4B into a vpn router
-
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?

You're not going to have fun when using OpenVPN. Even Wireguard will be a stretch. The Raspberry Pi does not have any hardware cryptography acceleration built-in and the raw compute power is very limited.

I already have a pi4B just wanted to find a use case for it. Is it really that bad? so how consumer routers with a fifth computing power run vpns?

Can I run OpenVPN configs on it and use it as a roiter

Just install Raspbian and PiVPN and forward the right ports dude; Less complicated

Sell it and get something more suited to the task instead of trying to shoehorn it onto a pi.

With hardware acceleration.
Computing power isn't just a general quantity. Networking devices have dedicated chips in them to perform various parts of processes. (Encryption, decryption, encoding, decoding, compression, decompression, etc.)
That's hardware acceleration. There are chips that are super efficient and powerful but they can only do that one thing.
That's fine if you know exactly what the device is going to be for, so you can put in the exact chips it needs to do only what it needs to do.

Makes sense Well explained thanks. I guess I'll find a dedicated VPN router

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 think you're right. I guess I need a wired router that can run OpenVPN on stock firmware or supported by and OpenWRT can be installed on it and has the hardware needed to run OpenVPN clients. The problem is I don't know what to buy now and honestly where I live there are not many options

Can you just get your own Router and use that instead of the ISP one? Then you can flash whatever firmware you want on it and you can run the openvpn/wireguard client at the router level. You won't need to combine the Pi with it.

I think GL.inet has tiny ones you can use.

What should I buy that supported by OpenWRT?
-
Define great. Tailscale doesn't even run Wireguard on the kernel level, but in user space.

gl.iNet definitely shows your expected VPN speed (OpenVPN and Wireguard) on their product pages, which is great.
Still, if you need gigabit speeds, those devices usually can not provide that. -

Ran WireGuard on a Pi1 and it was fine for two users.
A 4b should be more than enough for many use cases except torrenting. It really depends on the workload.

I think most consumer routers let you flash firmware. I believe certain Asus ones do, but obviously just validate that before buying it. OpenWRT has a list of supported devices you can check.
I just figured that if you're doing network stuff then you'd likely want to use something other than the ISP router as those track your activity more (this is a privacy community after all) and lock many features you may need.

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.
