Changes

2.0rc10
  • LANG variable is now used to display 'ifconfig' output in the English language.
  • Firewall now shows the public address in the exit message when FIREWALL_IP is enabled.
  • Improved error messages for STATIC_INSIDE_OUTSIDE.
  • Updated instances of deprecated coreutils syntax, e.g. "head -#" was changed to "head -n #".

To Do

2.0rc10
