iptables: always allow port 80

[Sebastian Rose <sebastian_rose@gmx.de>]

Questions for iptables specialists:


1.) iptables -I DENYCC 4 -m tcp --dport 80 -j ACCEPT

   Is a rule like this acceptable?
   Should I use --limit?

2.) Which MAC address does the server see?
    Will it always be the MAC address of my customers machine? 


Thanks in advance,

   Sebastian
