18
Traceroute will trace routing path, if achieves the target address, that means Gateway is
online.
DNS
DNS will analytic a domain, if it works, that means Gateway is online.
Note: the default setting is Ping, which is highly recommended, as traceroute will cost
dataflow of SIM card, while DNS is faster, but as it has cache, it may shows the Gateway
is online even it is offline.
2) Primary Detection Server
It can be an IP address or a Domain Name.
3) Second Detection Server
If primary detection server fails, then Gateway will auto switch to second detection server.
4) Retry Times
You can set up retry time in case detection fails.
5) Retry Interval
The interval time between 2 detection.
6) Enable Reboot
Click enable, and Gateway will reboot within the time set if it fails to reconnect.
7) Reboot After Interval
You can specify the time of offline, to reboot the Gateway.
3.1.5 Diagnostics
There are 3 types of network diagnosis: ping, traceroute and dnslookup
Parameter of ping and traceroute can be a Domain Name or an IP address, used for
checking if Gateway is online or not. While Dnslookup is to analytic domain.
