I am doing iptables firewall configuration. Actually, I need to allow ssh connection only from particular IP. But, It is blocking the ssh connection.

I used the below commands.

sat:~# iptables -F
sat:~# iptables -A INPUT -p tcp -s src_ip_address -d my_ip_address --dport 22 -m state --state NEW,ESTABLISHED -j ACCEPT
sat:~# iptables -A INPUT -j DROP
sat:~# iptables -nL
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         
ACCEPT     tcp  --  src_ip_address       my_ip_address       tcp dpt:22 state NEW,ESTABLISHED
DROP       all  --  0.0.0.0/0            0.0.0.0/0           

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination 

If I try to connect from src_ip_address to my_ip_address, it is blocking the connection. Even, It is blocking from my_ip_address to src_ip_address . I haven't put any rules for OUTPUT chain.

What is wrong with my commands?

How to allow ssh in iptables?
