What would you say is the best current Link Balancer solution out there?
I love Peplink's (peplink.com) link balancing router. We tried the Barracuda as we really like their Web and Email appliances, but it was too new and couldn't really handle the advanced situations we needed. Plus, the peplink has a really slick interface.
This might be a great appliance to look at? Barracuda Networks Link Balancer
I have used Barracuda Spam and Web filters with great success and I highly recommend them.
