2811 with 2 xDSL circuits, NAT and Default route configuration
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.
Re: 2811 with 2 xDSL circuits, NAT and Default route configurati
Hi, no not yet, I ran out of time whilst on site.
But, one thing I did see, I pointed the default routes out to the dialer interfaces, there are 2, 1 for each dsl interface. checking the ip route table there were 2 DF routes, both dialer interfaces were up even though only one dsl was active. Again, I've not been able to look at this since, am going to set it up a lab.
I've been told that I should be able to configure 2 NAT processes, one per interface, so that bit should have worked.
