Hello All!
I just purchased a Intel Celeron box from AliExpress to replace (and hopefully improve) the functions of my raspberry pi running wg-easy and pihole. I’d like this new box to handle DHCP, firewalling/ad blocking, and act as my wireguard server.
Currently I’m connecting my Internet modem (thankfully not a router, so no NAT) to my TPlink Archer AX21’s WAN port and then using the LAN ports to connect to my devices. I see that I can turn off NAT on the TPLink, but I assume I wouldn’t be able to use the new device as a DHCP server if I do, right? I could put the TPLink in AP mode but I’m not sure if that shuts off the WAN or LAN ports.
Is the best move to leave the TPLink in router mode (I’m not sure this matters) and plug the firewall into one of the LAN ports? I can do this but it’ll require some re-running of cables so I wanted to check first.

If you’re comfortable running your own router, my suggestion would be to install Opnsense on the new celeron box (as long as it has multiple ports and all the drivers exist in FreeBSD) and keep the TPLink in AP mode so it only handles the wifi side of things Opnsense is incredibly powerful and should have no problem running as your DHCP/firewall/wg box. I don’t run pihole anymore since it has an Adguard Home plugin you can set up, but I did find it a bit more challenging to configure than pihole was

I have thought about that, the issue is I’d need to re-run all but 1 of my Ethernet cables to a place where I can put the Celeron box. Once I start messing around with VLANs this is probably what I’ll do, but it’s going to be a big project.
I’m definitely going to give Adguard Home a shot.
Any thoughts on the best solution for now, basically putting the firewall in between the router and modem? If I plug it into the LAN port and set up DHCP so it is the new gateway, that should work, right?

Just to confirm, you don’t have space next to your modem and/or router for the new Celeron box, correct?
I’m not sure how good of performance you would have if you run the firewall on the Celeron box connected to the LAN portion of your current router, but you could always give it a shot and if it doesn’t work the way you’d like it to then you could try a different solution. From my understanding this setup would cause all traffic to go through your router at least 2x (even if it’s only on layer 2 via the built-in switch.) it may not be that much of a drain though, I’ve never run a setup like that before
The best layout would be modem -> opnsense router -> Tplink device running in AP mode. From what you’ve said that doesn’t sound feasible at this time. You might be able to utilize a bridge mode somehow, but at that point I’d be guessing since I don’t remember much about the tplink consumer router capabilities
