We have a single site customer with a 2821 router with a T1 internet connection. They recently added another internet connection which is a wireless broadband connection with 2Mbps/1Mbps rates. My goal is to be able to utilize both internet connections to load balance the traffic as well as using the T1 as the primary and the wireless as secondary if the T1 goes down. We have a NAT pool setup and some static translations on the T1 addresses for things like the internal mail server, VPN, etc. What are some of the things to be cautious about when trying to set this up?
There are several things to be cautious about in the situation that you describe. One is the possible impact of assymetric paths. This occurs when data goes out over one connection and the response comes back over the other connection. Another possible issue is whether the translations that you are doing for traffic out the T1 would also work for the secondary connection or whether different translations are called for.
