Multiple LAN firewall rule

Question

I am trying to find a simple firewall rule where all LAN ports can see other LAN ports. Each LAN port assign their own DHCP subnet mask 
 
 LAN1 - 192.168.1.0 
 LAN2 - 192.168.2.0 
 LAN3 - 192.168.3.0 
 LAN5 - 192.168.5.0 
 LAN7 - 192.168.8.0 
 
 I can make firewall rule LAN1/ANY/LAN2 then LAN2/ANY/LAN1 and goes on to LAN7 but it is silly to make 50 rules.. I even tried LAN1-7/ANY/LAN1-7 and it worked one way not other way... 
 I need to make sure any LAN can see any LAN

Basically you can use LAN to LAN as a zone based rule. 
 If you want to be more specific, you need to go back to the whiteboard and think about the structure. 
 XG will drop if it does not find any matching rule and uses first match rules. 
 
 So you can do following: 
 
 LAN to LAN with LAN1 to LAN2 with ANY Services allow 
 LAN to LAN with ANY to ANY with Service DNS allow 
 
 So LAN1 to LAN2 can talk with any services. And All LANs can talk with DNS to each other. As a example.
