After a few nights of meddling with my configuration, the following setup is working well for me. I would like to share it with the community.
Perquisites
- Ask support for a unique IP address for the dialer interface of each of your ADSL lines
- You will also need a static block for your routing IP address and any external clients, you may also use one of these addresses for NAT (more on that later).
- Configure Clueless to route your static block down each of the ADSL lines
My Setup
- Three ADSL lines provided by AAISP
- Cisco 2821 running IOS 15.1
- Three WIC1-ADSL and an NM-ESW-16 switch module.
- Internal ADSL interfaces allow me to run the setup in PPPoA mode. Modify your dialers for PPPoE if you are using external bridges.
Configuring your Dialer interfaces

Configure a virtual interface for your router IP address
Use the first address from your block
interface Vlan2 ip address <fromyourblock> <yoursubnet>
Upstream load balancing using CEF
ip cef ! ip route 0.0.0.0 0.0.0.0 Dialer0 ip route 0.0.0.0 0.0.0.0 Dialer1 ip route 0.0.0.0 0.0.0.0 Dialer2 ! int Dialer0 ip load-sharing per-packet ! int Dialer1 ip load-sharing per-packet ! int Dialer2 ip load-sharing per-packet !
