You're dropping all incoming TCP traffic! This must be switched.
And you should use conntrack (it replaces state).

    -A INPUT -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT
    -A INPUT -j DROP

But I'm not sure if this is necessary at all. You could accept
all incoming traffic.

I haven't tested it so I'm not sure it will work.
