(pppoe-out1 is I suppose Your DSL connection)

Thanks m4rk0,

I think I understand the lines setting up the gateways with distance 1 and 2. Distance 1 will be the primary gateway and 2 the fail over.

I would like to use my 411U with the G3 modem as my backup connection to the internet. So RB750 is my primary router and the DSL connection my primary internet connection.

I would like to avoid setting up a NAT / firewall in the RB411U if it can be avoided and continue to do all the routing in the primary router.

But how will i set up the gateway in the RB750 so that it finds it’s way to the RB411U and out to the internet?

Thanks,

Pilgrim
