7. 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-5001 ". And enter the Domain Name string
like "planet.com.tw" in the firmware version 1.391B. Then the System Name will present as "MH-5001 .planet.com.tw". After
upgrading firmware to upper version (ex. 1.50R). It will appear blank in the Source-IP field of System Logs.
8. 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.
