Note
If you have configured your SG560, SG565 or SG580’s switch as separate ports, and are
establishing multiple PPPoE ADSL Internet connections using two or more of these ports,
it is important that each port is connected to a remote device with a unique MAC address.
This is almost definitely the case if each of the Internet connections are through different
ISPs, otherwise you may have to request this specifically from your ISP.
If this is not possible, set each of the ADSL modems to routing or NAT rather than
bridged mode. Typically this means the ADSL modem terminates the PPPoE
connection, and the SG appliance is configured with DHCP or manually assigned
settings, using the ADSL modem as a gateway.
The Internet connections need not be the same, e.g. you can perform load balancing
between a PPPoE ADSL connection on one network port, and a Cable Internet
connection on the other.
Enabling load balancing
Under the Failover & H/A tab, click Modify Levels.
