ActiveLAN

ActiveLAN is an easy-to-use IP Switcher tool for logical switchover between several LANs/WLANs on multi-homed hosts under Windows. One of several adapters or connection profiles can be enabled dynamically (on-demand). While switching between the profiles, the tool changes automatically in the same step the proxy settings of the Internet Explorer and Mozilla Firefox, so that the proxy settings in your browser become adapted for the used LAN.
