Assets
Use GeoSite and GeoIP records as reusable routing material.
Assets are reusable lists of destination records. GeoSite records describe domain groups. GeoIP records describe IP ranges. After adding assets, the Rule editor can search their records and attach them to routing rules.
When assets help
GeoSite
A maintained group of domain records.
Good fit You want to route or block a site family, country list, category, or provider-maintained domain set.
Not ideal One exact domain is enough.
GeoIP
A maintained group of IP ranges.
Good fit You need rules for country, provider, private, or network ranges.
Not ideal The destination is better identified by domain.
Add and use an asset
Add Predefined fetches the first records
Add Predefined is a bootstrap action for an empty asset setup. It creates GeoSite and GeoIP entries and immediately fetches both over the network. The GeoSite entry uses the geosite.dat source and starts with Minification off. The GeoIP entry uses the geoip.dat source and starts with Minification on. If a matching predefined source already exists, Tunna skips the duplicate instead of adding it again.
Use trusted asset sources
Assets can influence many routing rules at once. Add remote assets only from sources you trust, and expect large lists to take time, storage, and network data to fetch and process.
