We have a customer who has 2 broadband lines in their office on the same network. They use a specific piece of software that needs to connect using "line 2" which is a dedicated line for their software. They use a route add on each machine to direct the traffic for the specific external IP range to that line.
What could we do for them to allow them to direct traffic through line 2 when outside the office - so they can use laptops.
Obviously a VPN was the first thought, but that would just route the traffic to the main line - it wouldn't route it back out again on line 2 i don't think.
