Welcome to the Snare Wizard
...
- Enable or disable the Basic Snare Firewall, which uses the UFW firewall to configure IPTables. For normal Snare Central operation, the firewall should be left enabled; it will only block those ports that do not have an associated snare-related service active.
When the Snare Firewall checkbox is enabled, the currently active firewall rules will be shown in the Active Rules section, and the Backup & Restore section is available. It is possible to make a backup of the current rules and restore them if required.
- Clicking on any active rule will display the "edit rule" form, where you can delete the selected rule or change parameters like destination port number, transport protocol, policy and origin.
- It is important to note that when adding a new rule, by default UFW will create the same rule for both TCPv4 and TCPv6. However, when deleting a rule you need to delete the TCPv4 and TCPv6 rules separately.
