good day gurus, i would like to setup and deploy 2 pfsense box

LoadBalancer (Box A) –---- > Squid (Box B) ----------> LAN

my question is , is it necessary to make the 2 boxes in same subnet? What i mean is, what IP Addresses that i will use on the two boxes?

Option A. 192.168.0.1 (BOX A) ------- > 192.168.1.1 (Box B) ----- > LAN
or

Option B. 192.168.1.1 (Box A) (DHCP Server on) ----------- > 192.168.1.2 (Box B) (DHCP Server Off) (Transparent Firewall) ----> LAN

Thank you in advance
