3 # banIP - ban incoming and outgoing IP addresses/subnets via Sets in nftables
6 IP address blocking is commonly used to protect against brute force attacks, prevent disruptive or unauthorized address(es) from access or it can be used to restrict access to or from a particular geographic area — for example. Further more banIP scans the log file via logread and bans IPs that make too many password failures, e.g. via ssh.
9 * banIP supports the following fully pre-configured domain blocklist feeds (free for private usage, for commercial use please check their individual licenses).
10 **Please note:** By default every feed blocks all supported chains. The columns "WAN-INP", "WAN-FWD" and "LAN-FWD" show for which chains the feeds are suitable in common scenarios, e.g. the first entry should be limited to the LAN forward chain - see the config options 'ban\_blockpolicy', 'ban\_blockinput', 'ban\_blockforwardwan' and 'ban\_blockforwardlan' below.

104 ## Installation & Usage
105 * Update your local opkg repository (_opkg update_)
106 * Install banIP (_opkg install banip_) - the banIP service is disabled by default
107 * Install the LuCI companion package 'luci-app-banip' (opkg install luci-app-banip)
108 * 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
109 * 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
110 * 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
111 * 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)

298 list ban_logterm 'SecurityEvent=\"InvalidAccountID\".*RemoteAddress='
299 list ban_logterm 'received a suspicious remote IP '\''.*'\'''
302 **allow-/blocklist handling**
303 banIP supports local allow and block lists, MAC/IPv4/IPv6 addresses (incl. ranges in CIDR notation) or domain names. These files are located in /etc/banip/banip.allowlist and /etc/banip/banip.blocklist.
304 Unsuccessful login attempts or suspicious requests will be tracked and added to the local blocklist (see the 'ban_autoblocklist' option). The blocklist behaviour can be further tweaked with the 'ban_nftexpiry' option.
305 Depending on the options 'ban_autoallowlist' and 'ban_autoallowuplink' the uplink subnet or the uplink IP will be added automatically to local allowlist.
306 Furthermore, you can reference external Allowlist URLs with additional IPv4 and IPv6 feeds (see 'ban_allowurl').
307 Both local lists also accept domain names as input to allow IP filtering based on these names. The corresponding IPs (IPv4 & IPv6) will be extracted and added to the Sets. You can also start the domain lookup separately via /etc/init.d/banip lookup at any time.
309 **allowlist-only mode**
310 banIP supports an "allowlist only" mode. This option restricts the internet access from/to a small number of secure MACs, IPs or domains, and block access from/to the rest of the internet. All IPs and Domains which are _not_ listed in the allowlist (plus the external Allowlist URLs) are blocked.
313 banIP supports concatenation of local MAC addresses with IPv4/IPv6 addresses, e.g. to enforce dhcp assignments. Following notations in the local allow and block lists are allowed:
316 C8:C2:9B:F7:80:12 => this will be populated to the v4MAC- and v6MAC-Sets with the IP-wildcards 0.0.0.0/0 and ::/0
318 MAC-address with IPv4 concatenation:
319 C8:C2:9B:F7:80:12 192.168.1.10 => this will be populated only to v4MAC-Set with the certain IP, no entry in the v6MAC-Set
321 MAC-address with IPv6 concatenation:
322 C8:C2:9B:F7:80:12 2a02:810c:0:80:a10e:62c3:5af:f3f => this will be populated only to v6MAC-Set with the certain IP, no entry in the v4MAC-Set
324 MAC-address with IPv4 and IPv6 concatenation:
325 C8:C2:9B:F7:80:12 192.168.1.10 => this will be populated to v4MAC-Set with the certain IP
326 C8:C2:9B:F7:80:12 2a02:810c:0:80:a10e:62c3:5af:f3f => this will be populated to v6MAC-Set with the certain IP
328 MAC-address with IPv4 and IPv6 wildcard concatenation:
329 C8:C2:9B:F7:80:12 192.168.1.10 => this will be populated to v4MAC-Set with the certain IP
330 C8:C2:9B:F7:80:12 => this will be populated to v6MAC-Set with the IP-wildcard ::/0
332 **enable the cgi interface to receive remote logging events**
333 banIP ships a basic cgi interface in '/www/cgi-bin/banip' to receive remote logging events (disabled by default). The cgi interface evaluates logging events via GET or POST request (see examples below). To enable the cgi interface set the following options:
335 * set 'ban_remotelog' to '1' to enbale the cgi interface
336 * set 'ban_remotetoken' to a secret transfer token, allowed token characters consist of '[A-Za-z]', '[0-9]', '.' and ':'
338 Examples to transfer remote logging events from an internal server to banIP via cgi interface:
340 * POST request: curl --insecure --data "<ban_remotetoken>=<suspicious IP>" https://192.168.1.1/cgi-bin/banip
341 * GET request: wget --no-check-certificate https://192.168.1.1/cgi-bin/banip?<ban_remotetoken>=<suspicious IP>
343 Please note: for security reasons use this cgi interface only internally and only encrypted via https transfer protocol.
345 **redirect Asterisk security logs to lodg/logread**
346 banIP only supports logfile scanning via logread, so to monitor attacks on Asterisk, its security log must be available via logread. To do this, edit '/etc/asterisk/logger.conf' and add the line 'syslog.local0 = security', then run 'asterisk -rx reload logger' to update the running Asterisk configuration.
348 **send status E-Mails and update the banIP lists via cron job**
349 For a regular, automatic status mailing and update of the used lists on a daily basis set up a cron job, e.g.
351 55 03 * * * /etc/init.d/banip report mail
352 00 04 * * * /etc/init.d/banip reload
355 **tweaks for low memory systems**
356 nftables supports the atomic loading of firewall rules (incl. elements), which is cool but unfortunately is also very memory intensive. To reduce the memory pressure on low memory systems (i.e. those with 256-512Mb RAM), you should optimize your configuration with the following options:
358 * point 'ban_basedir', 'ban_reportdir' and 'ban_backupdir' to an external usb drive
359 * set 'ban_cores' to '1' (only useful on a multicore system) to force sequential feed processing
360 * set 'ban_splitsize' e.g. to '1000' to split the load of an external Set after every 1000 lines/members
361 * set 'ban_reportelements' to '0' to disable the CPU intensive counting of Set elements
363 **tweak the download options**
364 By default banIP uses the following pre-configured download options:
366 * aria2c: --timeout=20 --retry-wait=10 --max-tries=5 --max-file-not-found=5 --allow-overwrite=true --auto-file-renaming=false --log-level=warn --dir=/ -o
367 * curl: --connect-timeout 20 --retry-delay 10 --retry 5 --retry-all-errors --fail --silent --show-error --location -o
368 * wget: --no-cache --no-cookies --timeout=20 --waitretry=10 --tries=5 --retry-connrefused --max-redirect=0 -O
369 * uclient-fetch: --timeout=20 -O
371 To override the default set 'ban_fetchretry', 'ban_fetchinsecure' or globally 'ban_fetchparm' to your needs.
373 **send E-Mail notifications via 'msmtp'**
374 To use the email notification you must install & configure the package 'msmtp'.
375 Modify the file '/etc/msmtprc', e.g.:
388 from <address>@gmail.com
392 Finally add a valid E-Mail receiver address.
394 **change existing banIP feeds or add a new one**
395 The banIP default blocklist feeds are stored in an external JSON file '/etc/banip/banip.feeds'. All custom changes should be stored in an external JSON file '/etc/banip/banip.custom.feeds' (empty by default). It's recommended to use the LuCI based Custom Feed Editor to make changes to this file.
396 A valid JSON source object contains the following information, e.g.:
400 "url_4": "https://raw.githubusercontent.com/SecOps-Institute/Tor-IP-Addresses/master/tor-exit-nodes.lst",
401 "url_6": "https://raw.githubusercontent.com/SecOps-Institute/Tor-IP-Addresses/master/tor-exit-nodes.lst",
402 "rule_4": "/^(([0-9]{1,3}\\.){3}(1?[0-9][0-9]?|2[0-4][0-9]|25[0-5])(\\/(1?[0-9]|2?[0-9]|3?[0-2]))?)$/{printf \"%s,\\n\",$1}",
403 "rule_6": "/^(([0-9A-f]{0,4}:){1,7}[0-9A-f]{0,4}:?(\\/(1?[0-2][0-8]|[0-9][0-9]))?)$/{printf \"%s,\\n\",$1}",
404 "descr": "tor exit nodes",
409 Add an unique feed name (no spaces, no special chars) and make the required changes: adapt at least the URL, the regex and the description for a new feed. The flag is optional, currently only 'gz' is supported to process archive downloads.
