DDNS 4 Admin

Restrict client login/admin access using domain names (D/DNS, reverse DNS and other). Extends IP-Geo-Block plugin.

Features

• DDNS/DNS Host Names:
  When your client Host has DNS or Dynamic DNS name, then resolved host name is automatically added to IP Whitelist of IP-Geo-Block.

  Use case 1):
  If your client host has changing IP (Dynamic DNS) or you do not want to enter IP number into Whitelist (classic DNS), then configure DDNS-4-Admin by entering your client Host Name. Optionally disable IP-Geo-Block country codes by entering ‘YY’.

  Use case 2):
  To allow login/admin access from client host name in not-allowed country, configure DDNS-4-Admin by entering that client Host Name (DNS)

• DDNS/DNS Lookup Caching:
  Allowed client IP numbers are cached. Enter maximum time in sec to keep DNS resolved IP numbers cached.

• Reverse-DNS Host or Network Name:
  When your client Host has Reverse Host Name (i.e. set by your ISP) then login/admin access to client Network or Host is allowed by matching reverse lookup of Host Name.
  Attention: Reverse host name is usually different than DNS host name

  Use case:
  In a large country IP-GEO location may not be restrictive enough. Then use this filter to restrict client hosts to your ISP or IP network. Optionally disable IP-Geo-Block countries by entering YY as Whitelist country code.

  ie: ‘my.work.pc.example.com’
  Matches host with ‘*my.work.pc.example.com’ reverse name
  ie: ‘.example.com’
  Matches all hosts with reverse name ending with ‘.example.com’
  ie: www.example.com, user.example.com, my.work.pc.example.com etc.
  ie: ‘.adsl.isp.provider.example.net’
  Match only clients from your adsl provider with reverse name
  ie: 12.43.55.66.adsl.isp.provider.example.net

  Allowed client IP numbers are cached by IP-Geo-Block plugin.
