UTM configuration with Verizon FIOS

Question

Trying to setup UTM 9.3 with Verizon FIOS. I currently have connected as follows: 
 Verizon FIOS router LAN port --> UTM WAN port (eth2) -->UTM LAN port (eth1) --> switch --> Wireless router LAN port (used as access point). 
 The verizon router is 192.168.1.1 with DHCP enabled for range 192.168.1.100 - .200 (do I need DHCP here? I do have a couple of devices directly connected to this router bypasing UTM) 
 I have UTM LAN set to 192.168.1.2. It seems I may need to enable DHCP here since downstream clients are not getting address from Verizon router. I tried enabling DHCP with range 192.168.1.10 - .99 with no luck 
 All subnet masks are 255.255.255.0. I will need all internal LAN devices to reach each other - a wireless client connected to the router needs to hit a printer connected to the Verizon router, etc. 
 The wireless router is set to 192.168.1.3 no DHCP thinking it would pick up address from something upstream. 
 I'm currently not getting internet access downstream of UTM. Using Tools-->Ping check on UTM I can ping internet addresses by IP but not by name. 
 Suggestions greatly appreciated.

I have a similar setup... 
 
 Leave DHCP turned on on the Verizon router. The cable boxes need the addresses from here. 
 
 The issue is the WAN and LAN interfaces on the UTM need to be on separate networks. 
 
 So, what you could do is: 
 1) Change the IP address of the UTM LAN to 192.168.2.1 
 You will lose your connection to the UTM at this point. 
 2) Change your IP address to 192.168.2.100 
 3) Reconnect to the UTM (192.168.2.1) 
 4) Turn on DHCP on the UTM 
 Range is 192.168.2.100 to 192.168.2.200 
 Subnet mask is 255.255.255.0 
 DNS is 8.8.8.8 and 8.8.4.4 (These are Google's DNS servers) 
 Default gateway is 192.168.2.1 
 5) Save your settings, then turn your machine back to automatic for IP and DNS.
