I'm working on a network-level AdBlocker project functionally similar to Privoxy which requires 2 Ethernet ports. One connecting to the modem and the other connecting to the router so that it's possible to MITM the traffic, but I don't see any boards with 2 Ethernet ports. Should I:

- buy 2 ESP32s with an Ethernet port on each and communicate between them over serial

- buy an ESP32 with Ethernet and USB and use an Ethernet to USB adapter

- or is there a better option?
