First some of the details. We are a SME (80 office users 30 remote) with 2, soon to be 3 WAN connections. Our WAN connections are a T1, Cable (25/5), and soon to be DSL (10,2). We are looking to to provide automatic WAN link failover for inbound services across all of our WAN links.
I feel that some of the WAN link balancing products currently on the market should be able to fit our needs, however I'm looking for any input anyone has on how to best address inbound automatic link failover. I would like to try to stay away from BGP, as our in house expertise is thin in the area.
So I'm looking for your opinions on what the current best approach for inbound automatic link failover. What have you done, or what have you heard is good?
