From 5af101564a9f889807e0e2762934e03cb0259eb1 Mon Sep 17 00:00:00 2001
From: Dirk Brenken <dev@brenken.org>
Date: Thu, 28 Dec 2023 17:56:38 +0100
Subject: [PATCH]  banip: update 0.9.3-2

* rework the device/interface auto-detection (only layer-3 network devices will be detetcted correctly), disable the auto-detection e.g. for special tunnel interfaces
* supports now full gawk (preferred, if installed) and busybox awk
* raise the default boot timeout to 20 seconds (if 'ban_triggerdelay' is not set)
* various small fixes and improvements
* readme update

 * Install banIP (_opkg install banip_) - the banIP service is disabled by default
 * Install the LuCI companion package 'luci-app-banip' (opkg install luci-app-banip)
 * It's strongly recommended to use the LuCI frontend to easily configure all aspects of banIP, the application is located in LuCI under the 'Services' menu
+* If you're using a complex network setup, e.g. special tunnel interfaces, than untick the 'Auto Detection' option under the 'General Settings' tab and set the required options manually
+* Start the service with '/etc/init.d/banip start' and check everything is working by running '/etc/init.d/banip status' and also check the 'Firewall Log' and 'Processing Log' tabs
 * If you're going to configure banIP via CLI, edit the config file '/etc/config/banip' and enable the service (set ban\_enabled to '1'), then add pre-configured feeds via 'ban\_feed' (see the feed list above) and add/change other options to your needs (see the options reference below)
