19/5000 DHCP, why this?

Dear:
Have a very good afternoon.
My query is as follows, I have a RB2011Uias, with DHCP configured.
I also have connected 2 LOCO M5 antennas for communication within the NETWORK.
I have a firewall rule where it captures the connections to ether5 which is my LAN.
My question is, because it shows me in the firewall rule the connections and in the LEASES table of DHCP does not ?.

Thank you

I am really struggling to understand what you asking, but anyway, the ip subnet in firewall rule is not the connection, but it is a subnet manually entered in firewall rule as one of the rules conditions
