Can I run a Minecraft server on a different Wi-Fi?

This is a 1.7.9 bukkit server, and I'm using a Mac. My cousin did it, but his server was regular minecraft. Is it possible, and how?

Btw, my cousin didn't have to port forward the different Wi-Fi to run his server.

Hi to be really effective a server needs to be on a leased line which is going to cost thousands of dollars or pounds. The bandwidth is the issue. So how you expect to use a Wi-Fi protocol to deliver such band widths is a joke.

It depends what you mean by "different Wi-Fi". It certainly is not going to work to Wi-Fi at a different home unless the proper port is forwarded to it on the router the server is on, so the minecraft client on other wireless can go through the interent to get to it.

The only way it would work without port forwarding is if the server was connected to wireless on one router (or wireless/router/modem) and the client was on of a 2nd router that has its WAN port wired to LAN port of the first router. Or it would work if the 2nd wireless was just a Wireless Access Point (instead of router), or a router dumbed down (DHCP disabled, etc.) to act like an access point connected LAN to LAN with crossover cable (although, I had pauses due to arp issues when I tried that).
