I've been asked to setup a 2811 router with 2 DSL connections into an ISP. The customer wants to load balance across the 2 outbound circuits, which I planned to do using 2 equal cost default routes. They also need to NAT/PAT the outbound traffic.
Setting this up on one DSL is no problem. It all starts to go wrong when I add the second DSL. I'm using two Dialer interface's, one bound to each xDSL, as the NAT/PAT source.
Adding a second NAT statement that uses the second dialer as the NAT source breaks the NAT completely, so I'm doing something wrong here. Is this valid, I'm told this should work.
The second issue is to do with default routes, I need to obtain the next hop information from the ISP dynamically, this didnt work as expected either. I tried using the DHCP option on the default route, but ran out time to test this, although it didnt appear to be working.
Any idea's, I'm sure this should work.
