Add support for HAProxy ACLs "src -f /ipalias.lst" to use pfBlockerNG IP Alias Native
At same time HAProxy can use pfSense Aliases as SourceIP list for ACLs. It has many use-cases, like:
- configure one alias for store all CloudFlare IPs and then respond 503 for any client not from that list
- use GeoIP to determinate client country and redirect he to localized version of website.
Unfortunately currently only static (manually created) aliases at HAProxy works. In case you will try pointing to pfBlockerNG Alias: you will get blank IPs list on filesystem.
Future request: can integrate pfBlockerNG IP Aliases to work with HAProxy?
Maybe additionally add option to pfBlockerNG to reload HAProxy on changes in pfBlockerNG Alias IP List.
