Hello,

I have sey up an IPSec VPN using a DSL line at the branch office to my central CPD. Now I'm going to have two DSL's at each branch office and I would like to load balance the VPN traffic among both lines, but I don't know if it's possible to do it straight away. Also, I need it to be able to fallback to the remaining DSL in case one goes down (I don't mind using a script for that if needed).

I was thinking on spliting the remote /24 into a couple of /25 and use different tunnels for each across both lines... Also, try to figure out whith ports may be more loaded and tunnel those using one DSL and the rest using the remaining one.

Has anyone done something like this? Do you have any other suggestions on how to properly balance the load among both lines?

Thank you!
