Countries
Country rules from RIR delegation statistics or MMDB files (e.g. DB-IP Lite, GeoLite2), with source attribution.
Geo-blocking
Geo-blocking for Windows Server – with local data
Your users work from a few countries? Then RDP does not need to be open to the whole world. ServerBouncer blocks per service and port by country, ASN or network type – without online lookups.
ASN and cloud
ASN from MMDB, cloud ranges of AWS, Azure, Google Cloud and Oracle from their published lists.
Tor, VPN, hosting
Tor exit lists and your own VPN or hosting lists as network type – for rules and for incidents on suspicious logons.
Local and traceable
You import the files yourself; ServerBouncer downloads nothing and queries no internet services. Country and ASN are shown in the block list, attempts and IP details. Geo rules complement detection – for RDP the hardening check still recommends access grants, because attackers can also come from allowed countries.
