I am on a LAN at work, connected with an ethernet cable.
Now, when I plug in my 3G Network Adapter (dongle), the Ethernet connection still has preference over the 3G connection.
Now I want connect certain applications via the 3G only, but it chooses the ethernet LAN gateway as the gateway to the internet.
So lets say I want to configure the proxy settings in Firefox to connect via the 3G, how do I do that? What address do I use and what port?
