[SOLVED] inter zone firewall rules

[bdario]

Hello folks,
I'm sorry for this basic question but I'm going to be crazy.
On my labo I have OPNsense 17.1.7-amd64 with 3 interfaces: wan / client / server

wan i/f 172.16.0.232/24 gw 172.16.0.1
client i/f 192.168.20.1/24
server i/f 192.168.1.1/24
the client IP 192.168.20.11
the server IP 192.168.1.100

In the server net I have a PC with Apache working good (the server)
In the client net I have a PC with windows 7 (the client)

browsing the server from the client I get the Apache2 Default Page (this means that the connection from the 2 lans is working fine
My first goal is to block the incoming connections to the server from the client net
I tried a lot of rules but I'm not able to block the traffic from the client to the server
Can anyone help me?
Best regards
Dario

Hello there
I think to solve the issue configuring a floating rule and applying it on client and server interfaces
