Mình nghĩ cái này bạn nên làm rồi tham khảo ý kiến mọi người sẽ tốt hơn cho bạn .
IP range cho cái LAN trên mình chia như vậy ( mình chia từ range IP lớn nhất tới nhỏ nhất )
LAN 2 : 172.31.0.0/22
range 172.31.0.1 --> 172.31.3.254 SM 255.255.252.0
Broadcast : 172.31.3.255
LAN 3 : 172.31.4.0/22
range 172.31.4.1 --> 172.31.7.254 SM 255.255.252.0
Broadcast : 172.31.7.255
LAN 5 : 172.31.8.0/24
