How to configure multiple WANs on a cisco 1812 IOS 12.4(2)XA

Hello,

I keep trying and trying to configure 2 WANs and 1 LAN in a loadbalance or round robin kind of way.
Does anyone know how to do this??

Thanks...

What kind of WAN do you have (e.g 2 Ethernet WAN interfaces? 1 Ethernet & 1 ISDN)?

I'll lay out the situation a little more:

I've got 2 SDSL connections, 1 DMZ and on LAN.

1st SDSL IP's 213.238.205.48/28
2nd SDSL IP's 193.173.116.48/28
DMZ IP's 192.168.160.0/24
LAN IP's 192.168.110.0/24

Everything works fine when I configure the CISCO with the following settings:
WAN port eth0 connected to the 1st ADSL with IP 213.238.205.50
DMZ has 1 public server configured with static NAT 192.168.160.3 -> 213.238.205.51
LAN is Dynamicly NAT'ed thru eth0 with WAN IP 213.238.205.50

As you can see there is no second WAN connection.
When I simply connect the 2nd SDSL thru WAN eth1 and configure NAT on eth1 with the following, Dynamic NAT: LAN ->  193.173.116.50, like the cisco help file says, nothing happens.
I can't even ping the SDSL modem/router on IP 193.173.116.49 from my PC, but when I ping thru the cisco SDM program it does ping succesfull.
Than I tried to add a second static default route with the following settings:
Prefix 0.0.0.0 Prefix Mask 0.0.0.0 IP Adress 193.173.116.49 Distance 1.

With this setting all the traffic seemed to be routed thru the second route but, it also uses the dns servers from the first connection and of course that doesn't work.

Try the following:

interface ethernet0
 ip load-sharing per-packet
 exit

interface ethernet0
 ip load-sharing per-packet
 exit


ip route 0.0.0.0 0.0.0.0 1st DSL
ip route 0.0.0.0 0.0.0.0 2nd DSL

Both routes should have the same metric.
