There are some advanced settings for the PPP dial up: the MTU and MRU. Leave it empty

3.4.2.3.2 Using both WAN0 and WAN1 (Load Balance and NAT
on the Internet interfaces)
You can use both WAN0 and WAN1 to configure your Internet connection. Both of their
interfaces provide NAT option and Load Balance settings.
The client devices will NOT be able to access the Internet through this interface once the
“NAT” option on it is set to Disabled.
If the “Load Balance” option is set to “Primary” on one of the interfaces (wan0 or wan1)
while another one set to “Secondary”, the secondary link will be a backup for the primary
one. In this scenario, the primary interface will provide Internet access to the client
devices, while the secondary one will be standby, and once the primary Internet link goes
down, the secondary one will automatically connect to the Internet and take place of the
primary one. When the primary link connects well to the Internet again, the secondary will
automatically shutdown the connection.
When both of the two interfaces were set to “Primary”, the MB9000 will balance the data
traffic between them.
