Why the Source-IP field of System Logs is blank?
Ans：
One reason is that you may enter Host Name and following by a space like "MH-5000 ". And enter the Domain
Name string like "planet.com.tw" in the firmware version 1.391B. Then the System Name will present as
"MH-5000 .planet.com.tw". After upgrading firmware to upper version (ex. 1.50R). It will appear blank in the Source-IP
field of System Logs.

When I ping the internet host from LAN/DMZ. I can't always finish the ping successfully. Sometimes it is work. But
sometimes it fails to ping the outside host.
Ans ：
This may cause there are more than one host in the LAN/DMZ pinging the same host at the same time. If one host
(Lan-A) is pinging internet host A(ex. 140.106.100.1), and at the same time, Lan-B is also pinging 140.106.100.1. Then
the pinging action of the Lan-A and Lan-B may fail. But when each host (Lan-A or Lan-B) is finish pinging, the other host
can continue the pinging action.
