If not possible, is there any workaround without affecting CPU performance?
iptables -A INPUT -p tcp --dport 80 -j DROP

If you don't use static ip but DHCP, you can filter on mac address in iptables. Something like :
iptables -A INPUT -p tcp --destination-port 80 -m mac --mac-source 00:0F:EA:91:04:07 -j ACCEPT
With your workstation mac address.
Have a look here : http://www.cyberciti.biz/tips/iptables-mac-address-filtering.html
Hope this help !

This will only work if both machines are in the same subnet. – mulaz Dec 11 '13 at 13:35

I did not test, but I believe it works. Perhaps any iptables workaround when not shared the same network? – Binyamin Dec 24 '13 at 17:17
