comment How to identify which website on my instance is receiving lots of traffic?

comment Configuring iptables: blocked out on SSH
Anyway, you can investigate the problem this way: flush iptables counters, then take a look at iptables counters while trying to connect from remote host. Thus you can see what rule exactly are applied to SSH packets.

comment NAT from Pvt ip to PublicIP
Definitely not. If you do not masquerade/SNAT, remote host could not response.
