Internet link load balancer
Hi Guys,
I am looking for a device with the capability to combine bandwidth from 2 ISP\internet connections from different providers.
I need this device to load balance the traffic, and at the very least when the primary link is reaching its capacity or having some intermittent issues the traffic should be routed to the secondary link.
Additionally the device will be able to use the secondary link in case that the primary link goes down.
I do have a currently 2 Firewalls in High Availability mode so the way I envision this device or (devices for HA) would be placed between my Firewalls and the ISP link connections.
Question:
What devices would you recommend for this setup?

Any firewall that supports a WAN Balancer would work for this. Might be worth trying the Untangle NG Firewall -- you can run this on your own hardware -- an older PC with three NIC's would work just fine -- or a newer PC if you need faster processing and higher bandwidths.

Virtual machine with openwrt or ddwrt (look up 'multiwan' in their documentation) should balance TCP/UDP, and fail over for other protocols.
This is the best picture that explains it, depending on your firewall models you can look up the exact configuration needs.
