After "iptables -P INPUT DROP in Ubuntu, How can apply my additional rule? : In Ubuntu 16.04LTS, 
I typed next lines.
iptables -F
iptables -X
iptables -A INPUT -m mac --mac-source 1C:**:2C:**:72:**:78 -j ACCEPT

and the result of "iptables -L -nvx" is
[the result of it][1]

but when I access to port 80 for accessing web-page with the PC(1C:**:2C:**:72:**:78), I cannot connect to the web-server.

When I try to the web-server with "iptables -P INPUT ACCESS", it works well.

Could anyone give me any solution or advicies for this?

Thank you for reading.

Have a good daay.
