sudo iptables -F && sudo iptables -P INPUT ACCEPT

linux · bash · Expert

Deletes every firewall rule and then sets the default inbound policy to accept. The host goes from filtered to fully exposed in one line, and the previous rule set is gone unless it was saved elsewhere.

Signals to notice

  • Flushes all firewall rules
  • Default policy set to ACCEPT
  • Prior rules are not backed up

Think you can spot these under time pressure?
