Bonded ADSL

Hi,


I want to increase the upload of all our VPN connections.

I wanted to know how this can be achieved using Bonded ADSL.

Currently we have a VPN setup between fortinet firewalls using 1 static IP at each site.


We have seen some multilink routers from Draytek etc, What i am trying to get my head around is how the VPN traffic will be managed through the internet if there are multiple ADSL lines at each site.


We are considering bonding 2-3 ADSL lines accross 5 sites and then VPN between them.

Depending on if you are located in the US, once you have bonded 3 ADSL lines at each site you likely end up with T-1 uploads as an aggregate, why wouldn't you just get an T-1 to the internet and skip the bonding and issues associated?  The cost will be roughly the same at each site and if you want redundancy then get a DSL connection.  As far as managing VPN traffic, look at white papers for Barracuda and/or Xnetworks.  Both of these provide link bonding solutions for multiple ISP connections.  Best of luck.
