X2 to x0 on sonicwall tz200

Hello.  I have a Sonic Wall TZ200, "Sonic Wall A" with an x0 (LAN) subnet of 192.168.3.1.  I have several computers connected to this subnet.  I have x2 on "Sonic Wall A" set up with and IP of 192.168.104.200 and I route that to another Sonic Wall TZ200, "Sonic Wall B" to the x2 port with an IP address of 192.168.104.100.  This is working fine and from any computer on "Sonic Wall A" 192.168.3.1 subnet I can manage "Sonic Wall B" using the 192.168.104.100 ip address.    

What I am now having trouble with is completing the connection from "Sonic Wall B" x2 (192.168.104.100) to "Sonic Wall B" x0 (192.168.103.1) with the ultimate intention of being to access a Network Video Recorder (NVR) with an IP of 192.168.103.25.
