Indirect bundling is performed over bundled PPTP connections, which means that the full bandwidth of the bundled channels can be used over the LAN-LAN link. When considering PPTP bundling, there are three different scenarios:
- The client bundles the DSL channels, the server is behind a connection with sufficient bandwidth
- The client is behind a broadband connection, and the server handles the bundling
- The server and the client bundle the DSL channels
All the configuration involves is including the other PPTP addresses into the balancing table.
