Check Load Balance for each connection to enable for load balancing. Click Finish.
Note
Load balancing settings are not specified for each failover level; load balancing occurs
when any two or more load balancing connections are up.
Limitations of load balancing
Load balancing works by alternating outgoing traffic across Internet connections in a
round robin manner. It does not bond both connections together to work as one link, e.g.
it does not bond two 512 Kbit/s links to function as a single 1 Mbit/s link.
Total bandwidth and available bandwidth are not taken into account when choosing a
connection on which to send outgoing traffic.
When an internal client makes a connection to a server on the Internet, this and
subsequent connections between the the internal client and remote server are confined
to the one Internet connection to ensure connections are not broken.
If a second internal client makes a connection to the same remote server, it may or may
not go across the same link, depending on which Internet connection is next to be
selected in the round robin process.
VPN connections such as IPSec or PPTP tunnels are confined to a single Internet
connection, as they are a single connection (that encapsulate other connections).
