I recently baught a CISCO 2800 series router with 2 adsl Cards.

What I want :

I have 2 ADSL lines (Public Dynamic IP)of 3 MB each.

1. The 200 odd users at my office should go through the ADSL line with load balancing i.e. traffic should be split equally between the two ADSL lines.

2. In case one any of the lines are down it should re-route the traffic through the available line.

(This is currently been achieved using our firewall but unfortunately this firewall is after the two unreliable routers supplied by ISP and these are the ones we want replace with a Cisco box)

Awaiting your reply.
