+Download, import and update firewall address-lists
+==================================================
+
+[⬅️ Go back to main README](../README.md)
+
+> ℹ️ **Info**: This script can not be used on its own but requires the base
+> installation. See [main README](../README.md) for details.
+
+Description
+-----------
+
+This script downloads, imports and updates firewall address-lists. Its main
+purpose is to block attacking ip addresses, spam hosts, command-and-control
+servers and similar malicious entities. The default configuration contains
+lists from [abuse.ch](https://abuse.ch/) and
+[dshield.org](https://dshield.org/), and
+lists from [spamhaus.org](https://spamhaus.org/) are prepared.
+
+The address-lists are updated in place, so after initial import you will not
+see situation when the lists are not populated.
+
+To mitigate man-in-the-middle attacks with altered lists the server's
+certificate is checked.
+
+Requirements and installation
+-----------------------------
+
+Just install the script:
+
+    $ScriptInstallUpdate fw-addr-lists;
+
+And add two schedulers, first one for initial import after startup, second
+one for subsequent updates:
+
+    /system/scheduler/add name="fw-addr-lists@startup" start-time=startup on-event="/system/script/run fw-addr-lists;";
+    /system/scheduler/add name="fw-addr-lists" start-time=startup interval=2h on-event="/system/script/run fw-addr-lists;";
+
+> ℹ️ **Info**: Modify the interval to your needs, but it is recommended to
+> use less than half of the configured timeout for expiration.
+
+Configuration
+-------------
+
+The configuration goes to `global-config-overlay`, these are the parameters:
+
+* `FwAddrLists`: a list of firewall address-lists to download and import
+* `FwAddrListTimeOut`: the timeout for expiration without renew
+
+> ℹ️ **Info**: Copy relevant configuration from
+> [`global-config`](../global-config.rsc) (the one without `-overlay`) to
+> your local `global-config-overlay` and modify it to your specific needs.
+
+Naming a certificate for a list makes the script verify the server
+certificate, so you should add that if possible. Some certificates are
+available in my repository and downloaded automatically. Import it manually
+(menu `/certificate/`) if missing.
+
+Create firewall rules to process the packets that are related to addresses
+from address-lists. This rejects the packets from and to ip addresses listed
+in address-list `block`.
+
+    /ip/firewall/filter/add chain=input src-address-list=block action=reject reject-with=icmp-admin-prohibited;
+    /ip/firewall/filter/add chain=forward src-address-list=block action=reject reject-with=icmp-admin-prohibited;
+    /ip/firewall/filter/add chain=forward dst-address-list=block action=reject reject-with=icmp-admin-prohibited;
+    /ip/firewall/filter/add chain=output dst-address-list=block action=reject reject-with=icmp-admin-prohibited;
+
+You may want to have an address-list to allow specific addresses, as prepared
+with a list `allow`. In fact you can use any list name, just change the
+default ones or add your own - matching in configuration and firewall rules.
+
+    /ip/firewall/filter/add chain=input src-address-list=allow action=accept;
+    /ip/firewall/filter/add chain=forward src-address-list=allow action=accept;
+    /ip/firewall/filter/add chain=forward dst-address-list=allow action=accept;
+    /ip/firewall/filter/add chain=output dst-address-list=allow action=accept;
+
+Modify these for your needs, but **most important**: Move the rules up in
+chains and make sure they actually take effect as expected!
+
+Alternatively handle the packets in firewall's raw section if you prefer:
+
+    /ip/firewall/raw/add chain=prerouting src-address-list=block action=drop;
+    /ip/firewall/raw/add chain=prerouting dst-address-list=block action=drop;
+    /ip/firewall/raw/add chain=output dst-address-list=block action=drop;
+
+> ⚠️ **Warning**: Just again... The order of firewall rules is important. Make
+> sure they actually take effect as expected!
