Hi guys,

If I've got two dedicated internet lines, one 4MB and one 10MB; so one is on X1 and the other on X2, then can I do any of the following:

1) Combine the two lines to make it 14Mb (inbound/outbound)?
2) Is it possible to combine it to 14MB ONLY for when it is outgoing traffic?

Many thanks for your help

You can't add the 2 lines to have a 14 Mb bandwith but you can use the "Failover & LB" configuration under "Network".
You can use the "Spill Over" config; When your first interface (10 Mb) is full used; the sonicwall will redirect the connection on the second line.

When you do this configuration, it will be only for outgoing traffic. Be carefull if you have incoming traffic: your server have to use the incoming line to send packets out ! To do this, you can add static route on your Sonicwall to say that your server A will always use the line X1 for exemple.
