I think you should have checked the iptables man page you must have
understood its very easy but still I will explain

Iptables [-t table] <action> <direction> -p <protocol> -s <source> network
adress> --dport <portno>  -j <ACCEPT/REJECT>

action = -A append or -I insert....rest lookup man page
direction= INPUT or  OUTPUT case sensitive
protocol= tcp or udp
source= 192.168.0.0/24 (e.g.)
port no = the port of service to apply on ( 22 for ssh) check /etc/services
for complete list

Regards
