      Steps to reproduce:

      1. No configuration changes needed
      2. Simple check "icmpping" returns down when alive from another host

      Result:

      Given below two examples (changed IPs from originals):

      $ fping 100.1.2.3
      100.1.2.3 is alive [<- 100.1.2.4]
      $ echo $?
      0

      $ fping 100.1.2.5
      100.1.2.5 is alive
      $ echo $?
      0

      The first that is responding from a different IP as alive shows as down in Zabbix. The second is one that responds normally as alive and shows as up in Zabbix.

      We are trying to monitor status of devices on a portion of the network that fping responds with the redirected IP, and are showing as down, even though on command line fping is successful. 

      Expected:

      Expect that both direct response and response from another IP would show as up.
