We set up temporary offices with 2 DSL connections. We have an ASA 5505 basic model which supports 3 VLAN’s so can configure a VLAN for each ISP.
We wish to direct general traffic through one DSL and HTTPS traffic through the other. This is because we have a significant HTTPS load to a specific DNS/URL.
Typical low-end routers do not support load balancing, and even high-end ones do not effectively handle HTTPS due to the authentication issues involved on source addresses.
