Multi-WAN for the bandwidth scalability

Multi-WAN Vigor Routers offers two modes for WAN Load Balancing, IP-Based is the default configuration. It divides traffic by IP address, which means all the sessions will take the same WAN interface as long as the source IP/port and destination IP/port are the same. And Session-Based divides the traffic by session. In the Session-Based mode, the router will distribute the sessions among WAN links, even though they are from the same connection, so the maximum bandwidth it can get will be the combination of all the active WAN.
