Haproxy custom acl whitelist and Specific IP Allow

ACL-Name-1         host matches:                      host1.example.com
Allow-Alias         Source IP matches Ip or Alias: 111.222.333.444

In the above we have two ACLs: host1 and adminIPs, for the adminIPs you can reference a pfsense alias instead of hard coding an IP if you need it to apply to more than one IP.
