I setup my iptables to look like this one below, I drop all incoming packet from the internet using port telnet, ftp,smtp and leave the port http,https, and ssh open. but on my lan i live all ports open and specify certain ip and netmask.
With this set of rules why i cant access HTTPS?
Is this set of rules on iptables safe now?
