## Tweaks
* there is no need to enable all blacklist sites at once, for normal use one to three adblock list sources should be sufficient
* if you really need to handle all blacklists at once add an usb stick or any other storage device to supersize your temp directory with a swap partition => see [openwrt wiki](https://wiki.openwrt.org/doc/uci/fstab) for further details
* add static, personal domain white- or blacklist entries, one domain per line (wildcards & regex are not allowed!), by default both lists are located in */etc/adblock*
* enable the backup/restore feature, to restore automatically the latest, stable backup of your adblock lists in case of any processing error
* enable the logging feature for continuous logfile writing to monitor the adblock runs over a longer period
* if you really need to handle all blacklists at once add an usb stick or any other storage device to enlarge your temp directory with a swap partition => see [openwrt wiki](https://wiki.openwrt.org/doc/uci/fstab) for further details
* add personal domain white- or blacklist entries as an additional blocklist source, one domain per line (wildcards & regex are not allowed!), by default both empty lists are located in */etc/adblock*
* enable the backup/restore feature, to restore automatically the latest stable backup of your adblock lists in case of any (partial) processing error (i.e. a single blocklist source server is down). Please use an (external) solid partition and *not* your volatile router temp directory for this
* for a scheduled call of the adblock service via */etc/init.d/adblock start* add an appropriate crontab entry
## Further adblock config options
* usually the adblock autodetection works quite well and no manual config overrides are needed, all options apply to 'global' adblock config section:
* adb\_enabled => main switch to enable/disable adblock service (default: '1' (enabled))
* adb\_enabled => main switch to enable/disable adblock service (default: '1', enabled)
* adb\_cfgver => config version string (do not change!) - adblock checks this entry and automatically applies the current config, if none or an older revision was found.
* adb\_wanif => name of the logical wan interface (default: 'wan')
* adb\_lanif => name of the logical lan interface (default: 'lan')
* adb\_port => port of the adblock uhttpd instance (default: '65535')
* adb\_nullipv4 => IPv4 blackhole ip address (default: '192.0.2.1')
* adb\_nullipv6 => IPv6 blackhole ip address (default: '::ffff:c000:0201')
* adb\_forcedns => redirect all DNS queries to local dnsmasq resolver (default: '1', enabled)
## Background
This adblock package is a dns/dnsmasq based adblock solution for openwrt.
Queries to ad/abuse domains are never forwarded and always replied with a local IP address which may be IPv4 or IPv6.
For that purpose adblock uses an ip address from the private 'TEST-NET-1' subnet (192.0.2.1 / ::ffff:c000:0201) by default.
Furthermore all ad/abuse queries will be filtered by ip(6)tables and redirected to internal adblock pixel server (in PREROUTING chain) or rejected (in FORWARD or OUTPUT chain).
All iptables and uhttpd related adblock additions are non-destructive, no hard-coded changes in 'firewall.user', 'uhttpd' config or any other openwrt related config files. There is *no* adblock background daemon running, the (scheduled) start of the adblock service keeps only the adblock lists up-to-date.
