Sonicwall TZ190 Help

Hi all – I have a puzzle and hope you can help me. I have 3 TZ190s 2 of which are on one LAN the third is in a remote office. I will refer to these as 1, 2, and 3.

Router 1 is my DHCP Server/Internet gateway on network 1. It is 192.168.7.xxx. Router 2 is defined as a VPN host for Router 3. Router 2 is also 192.168.7.xxx on LAN, and 192.168.10.xxx on the Inet port.

Router 3 is 192.168.8.xxx on LAN, and 192.168.10.xxx on Inet port. I have a 300 mbps wireless point to point connected to the inet interfaces of Router 2 and Router 3 with a vpn tunnel between them.

All applications run fine between the two sites, but I am trying to route all internet traffic from both offices through Router 1. Can anyone help me with this?

Thanks in advance –
