Moonshine_Iptables

A plugin for Moonshine

This plugin installs and configures iptables for your server. Just include the plugin and recipe, deploy, and you'll have a nice secure system.

By default, the firewall will:

  • Allow inbound ESTABLISHED and RELATED traffic
  • Allow inbound icmp, smtp, ssh, http, https
  • Allow inbound connections to unprivileged ports in the 8000-10000 range
  • Allow outbound connections to anywhere
  • Block everything else

Instructions

  • script/plugin install git://github.com/railsmachine/moonshine_iptables.git
  • To customize rules, use the configure method, passing the entire ruleset.

    
    configure(:iptables => { :rules => [
      '-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT',
      '-A INPUT -p icmp -j ACCEPT',
      '-A INPUT -p tcp -m tcp --dport 53 -j ACCEPT',
      '-A INPUT -p tcp -m tcp --dport 25 -j ACCEPT',
      '-A INPUT -p tcp -m tcp --dport 22 -j ACCEPT',
      '-A INPUT -p tcp -m tcp --dport 80 -j ACCEPT',
      '-A INPUT -p tcp -m tcp --dport 443 -j ACCEPT',
      '-A INPUT -s 127.0.0.1 -j ACCEPT',
      '-A INPUT -p tcp -m tcp --dport 8000:10000 -j ACCEPT',
      '-A INPUT -p udp -m udp --dport 8000:10000 -j ACCEPT'
    ]})
    
  • Include the recipe in your Moonshine manifest. recipe :iptables
