#netfilter IRC chat

There is a #netfilter IRC channel on Libera chat where you can hang out with Netfilter users and developers.

The netfilter core team

The netfilter core team is the group of people who actively maintains the netfilter framework. Please note, that this group is very small, and with an estimated number of millions of linux installations, we cannot help individual users with their firewall configuration. Regard this contact address as a last resort, if all other options have failed.

When to contact the core team?

  • If you found an important security-relevant bug and want to inform the vendor before releasing any information about it.
  • If you need professional support, development or consulting related to netfilter and iptables.
  • In case you have any question regarding licensing terms and compliance.
  • Again, the coreteam will _NOT_ respond to any simple usage/configuration questions. Such kind of questions will be ignored. PLEASE refer to the user mailinglist

You can contact the coreteam via (GPG key)
