I have just done what I was thought to be impossible with a router as bad as mine, but now I have proved that wrong.

Let me explain: I’m having problems with my DSL connection and I have a spare cable connection at home, which I wanted to route to more than just the computers on my wireless network. I needed a router with LAN and WAN ports.

My DSL router was just sitting there and as I googled for an answer, I found out it definitely was impossible.

But today I made what was said to be impossible, possible. I made my DSL router with NO WAN PORTS act as an average WAN router (without a DSL port). I made LAN port 4 act as a WAN port, and have a DHCP server + client (+NAT) running on it.

And I was just messing around with a telnet connection to the router. I have configured the router from CLI before, but never have I done it without a tutorial, nor have I done anything that extreme.

So, my question to you is this:
Have you ever made something happen while experts have said it could never be done?
If you have, what was it? Did you do it “because you can” or did you do it out of necessity?
