I own a MacBook Pro and always used Ubuntu in the past. In Ubuntu, I was able to configure my IP, DNS, Gateway, for a specific access point. There was a list of all the access points, each one with its own settings.
The goal I want to achieve is to do port forwarding in my own local network with static IP and still being able to connect with automatic DHCP settings somewhere else (not my own network).
But I'm unable to do/find this in Mac OS X. Is it possible (with or without extra applications)?
