Internet connection problem using a 3G card when ethernet cable is connected

Good morning,

 

I have just purchased a Lenovo X200, and installed the 3G card into the machine, it was working nice, but I have experienced some problems when trying to connect by the 3G connection when i am plugged with a ethernet cable to the network at work.

 

Explanation : At work i am having an internet connection by the ethernet cable, connected to a normal network, this internet connection has a filter not to enter in all the internet, so sometimes i need to go by the 3g connection ( opened to internet ) to look for some pages in the internet. When i try to connect to the internet by this 3G having plugged the ethernet cable, the computer does not enter into the internet, unless i unplugged the network cable.

 

Can anyone help me?

 

Many thanks

A quick way to solve is to use the dialup connection instead of the lan one.

 

So You will get de default gateway to the dialup connection and all should be working fine, with or w/o the wired lan attacched.

Google "multi-homed".  The problem is that you have two gateway addresses.
