Example 1: clients in the 172.24.0.0/24 domain cannot access your VM system.

(1)

[Root @ override top0 ~] # Firewall-cmd -- add-rich-rule "rule family =" ipv4"

Source address = "172.24.0.0/24" service name = "ssh" reject"

Success

[Root @ override top0 ~] # Firewall-cmd -- add-rich-rule "rule family =" ipv4"

Source address = "172.24.0.0/24" service name = "ssh" reject "-- per

Success

(2)

[Root @ server0 ~] # Firewall-cmd -- add-rich-rule "rule family =" ipv4"

Source address = "172.25.0.10" port = "3260" protocol = "tcp" accept"

[Root @ server0 ~] # Firewall-cmd -- add-rich-rule "rule family =" ipv4"

Source address = "172.25.0.10" port = "3260" protocol = "tcp" accept"

Example 2: In the 172.25.0.0/24 network, the local port 5423 accessing desktopX will be forwarded to 80.

[Root @ override top0 ~] # Firewall-cmd -- add-rich-rule "rule family =" ipv4"

Source address = "172.25.0.0/24" forward-port = "5423" protocol = "tcp" to-port = "80 ""

Success

[Root @ override top0 ~] # Firewall-cmd -- add-rich-rule "rule family =" ipv4"

Source address = "172.25.0.0/24" forward-port = "5423 "? Protocol = "tcp" to-port = "80" "-- per

Success

Example 3: allowed services
