No, the auxiliary port is not the same as a WAN port.

No. That is a serial port for router maintenance or low speed modems. Its maximum serial throughput is 115.2 kbit/s or ~0.1 mbit/s
wrong port. But yea I'd assume you can use it with a modem. IIRC that's fast ethernet, so you'd be limited to 100Mb/s. But I could be getting the model wrong in my head. Here's the manual since the absolute fuckwads at cisco think it's ok to delete all documentation on their website when the product has reached end of life. cisco 2800 series.pdf
It's not Ethernet—it's a serial connection for an analog dial-up modem. The router needs remote management outside of the band, which is why it's placed near the serial console. Many home network administrators confuse this setup with commercial networking equipment.
Also, please consider using command line settings since this device lacks a graphical interface. You'll have to locate the special router reset method to remove previous credentials. Additionally, you'll require a Cisco serial console cable to link with the router for setup.
I misunderstood the port assignment. It should include two regular fast Ethernet ports labeled FE 0/0 and FE 0/1, correct? I uploaded the manual for him, so he can review it if needed.
Immediately after I mentioned the wrong port, don’t tell me to fix it just because you want what you think. I’m referring to the router, which is what a sensible person would expect. He can operate the router, and I’m discussing this since he’s aiming to locate the correct ports and utilize the router. I assumed the router supports fast Ethernet—possibly gigabit—but I believe the 2800 series falls under that category. Look at the manual I shared if you need confirmation; it might indicate gigabit capability, though I’m not sure. In short, if this wasn’t clear initially, he should have been warned.
