Change network settings based on which network I'm connected to

I need a program which, when I connect to different networks (wired, through eth0), will switch my network profile according to the MAC of the router I'm connecting to. Any ideas?

• If the laptop is IBM/Lenovo, the "Access Connections" software does an acceptable job managing the connections. It can run programs, remember proxy settings, set default printer, and other things based on the network to which it is connected. I'm not sure if it uses the MAC address of the device or some kind of "port" identification.
