I have Cisco 1841 router with 2 adsl wic's ,2 Internet connections from the same ISP and i 'd like to do load balancing per-destination in the same lan. I have IOS 12.4(1a).
I 'm trying to set up fastethernet0/0 , 2 atm's and 2 dialers.
I want to setup with nat inside in fastethernet0/0 and nat outiside on both dialers,with pap authentication pvc 8/35 , ip address negotiated on dialers,
encapsulation aal5mux ppp dialer.
Can you help me with the config file?

Thank you very much nethelper.
I 'd like to ask you about the physical atm interfaces atm0/0/0 and atm0/1/0 .
I do not configure the atm0/1/0 interface ?
I have 48 pc's in the lan.
All the pc's they 'll share both connections from atm0/0/0 ?
For example:
PC01 going internet from connection ISP1
pc02 going internet from connection ISP2
pc03 going internet from connection with less load.
Best Regards

Hello,
the sample configuration given is based on two PVCs on the same physical interface. In your case, with physical interfaces ATM0/0/0 and ATM0/1/0, the configuration would look like this:
interface ATM0/0/0
no ip address
no ip redirects
no ip unreachables
no ip proxy-arp
ip route-cache flow
no atm ilmi-keepalive
!
interface ATM0/0/0.1 point-to-point
no ip redirects
no ip unreachables
no ip proxy-arp
pvc 8/35
encapsulation aal5mux ppp dialer
dialer pool-member 1
!
interface ATM0/1/0
no ip address
no ip redirects
no ip unreachables
no ip proxy-arp
ip route-cache flow
no atm ilmi-keepalive
dsl operating-mode auto
!
interface ATM0/1/0.2 point-to-point
no ip redirects
no ip unreachables
no ip proxy-arp
pvc 8/35
encapsulation aal5mux ppp dialer
dialer pool-member 2
The load balancing is per-destination (which is the default). That means that e.g. PC01 going to www.cisco.com will go through ISP1, PC02 going to www.microsoft.com will go through ISP2, and so forth.
