Own Router behind BGW210-700

Recently switched from cable internet to AT&T fiber.  Have own Sonicwall SOHO router with many settings I do not want to change.  Want to use the BGW210-700 as a 'modem-only' (to the extent possible).  Have experimented with the IP Passthrough mode of the BGW.  Successfully saw the WAN port in the Sonicwall get my public IP 99.xxx…. So far cannot get internet access on Sonicwall behind the BGW.

 

SONICWALL:

Router IP 10.10.10.10 static Mask 255.255.255.0

Public IP 99.xxx…. assigned by DHCP Mask 255.255.252.0

DNS 209.18.47.62 & 61

DHCP range 10.10.10.200 - 10.10.10.249

 

BGW (mainly defaults):

IP: 192.168.1.254 Mask: 255.255.255.0

DHCP range 192.168.1.64 - 192.168.1.253

Public Subnet off

Cascaded Router off

IP Passthrough Allocation Mode=passthrough

DHCPS-fixed

Passthrough Fixed MAC address (my Sonicwall's WAN MAC)

Passthrough DHCP lease 10 minutes

 

Can you find any errors in the above set up?  If I need to make private IP address changes, please tell me the changes needed on the  BGW.  I prefer to make as few changes as possible on the Sonicwall.  Thanks!!
