I am trying to use iptables but I am clueless in understanding the documentation even so that I've locked myself out of my server twice already whilst trying to implement it.

These are the simple rules that I want to implement:

  • Allow ports 80, 6667 and 6697 to everyone
  • Allow port 22 to just my IP for example

Please can someone help me implement these simple rules, without locking myself out?
