How to use 3 network connections at once


We are trying to utilize multiple network connections at one time. here is the scenerio.

We have a laptop that connects to ATT over an installed aircard (WWAN)
We use a cisco anyconnect vpn (over that aircard)
We connect dirrectly to a dvr machine over an ethernet connection
and want to also be able to connect to wireless (WLAN) to upload those videos

Any help? WHen we get more than 2 connections the third drops.

The important part here is that you can only have one default gateway. You can't assign a default Gateway on two of the connections.

You can use one connection with a default gateway so that your computer knows where to send request that are not on the same subnet (ie. the internet).

The other two connections can be on different private subnets but can't have a default gateway.

You were correct that the multiple gateways was causing a conflit.  We had to go without gateways on 2 of the connections (which was fine because the devices were local).

Thank you!
