* zero-conf like automatic installation & setup, usually no manual changes needed

* simple but yet powerful adblock engine: adblock does not use error prone external iptables rulesets, http pixel server instances and things like that

* automatically selects dnsmasq, unbound, bind or kresd (experimental!) as dns backend.

* automatically selects uclient-fetch or wget as download utility (other tools like curl or aria2c are supported as well)

* support http only mode (without installed ssl library) for all non-SSL blocklist sources

* automatically supports a wide range of router modes, even AP modes are supported

The knot-resolver (kresd) support is only available to turris omnia users. At this stage there's no package for kresd in the official LEDE / OpenWrt package repository.
|
||||
Adblock deposits the sorted and filtered block list (adb_list.overall) in '/tmp/kresd' where kresd can find them.
|
||||
To use the block list please modify the following kresd configuration files (experimental / untested!):
|
||||
|
||||
edit '/etc/config/resolver' and uncomment the following option:
|
||||
option include_config '/etc/kresd/custom.conf'
|
||||
|
||||
in the same file change the 'forward_upstream' option like that:
|
||||
forward_upstream '0'
