option "add", can be set to "insert <num>" instead of prepend (customization or backwards compat) 2021-05-06 20:23:58 +02:00
usernamepi e4e7a83cff
Update ufw.conf
Prerequisites:
* The ss command is available, kernel is compiled with option CONFIG_INET_DIAG_DESTROY.
* Ufw version is => 0.36 (released in 2018)

* Now using "prepend" instead of "insert" to be able to handle IPv6 addresses correctly. The current action will fail for IPv6 addresses.
* Now application names containing a space should handled correctly, solves https://github.com/fail2ban/fail2ban/pull/1532
* Now closing IPv4 and IPv6 connections (if any) from the ip that is being banned. The current action will leave them open.
   Using ss to accomplish this. For this to work the kernel needs to be compiled with the CONFIG_INET_DIAG_DESTROY option.
   My system apparently is compiled that way.
