-A RH-Firewall-1-INPUT -s 10.12.0.0/16 -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT

Ex- 10.12.0.0/16, 172.150.0.0/16, 192.168.20.0/24

How can we add multiple sources network address in the above INPUT chain?
Please anybody assist me. Thanks

Repeat command for each subnet

Code:

-A RH-Firewall-1-INPUT -s 10.12.0.0/16 -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A RH-Firewall-1-INPUT -s 172.150.0.0/16 -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A RH-Firewall-1-INPUT -s 192.168.20.0/24 -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
