Keeping Online function is used to check wireless gateway online status, this function checks periodically and automatically
data channel between gateway and wireless network whether normal or not. If it is found to be off-line, software will re-dial
automatically and intelligently, so that the device can always be online to make sure data channel smooth.
Wireless gateway supplies 4 kinds of online checking modes; customer can select one or more kinds. By default, Rule2 and
Rule3 are used.
Customer inputs stable "destination IP address" and "destination address port "and regards them as the reference of online
maintenance. Please kindly noted the input "destination IP address" and "destination address port" must be stable, because
wireless gate is referred to this server; if this server is not stable, it will cause wireless network off-line frequently. When multi
rules are used, only when all selected rules find communication line is obstructed, wireless gateway can judge whether device is
off-line or not and restart connection automatically

Rule 1: PING Mode
Figure 4-7-1 Rule and No Reboot
Description
Wireless gateway checks destination IP address through PING (ICMP) packet
periodically. When the referenced destination IP address device doesn't
respond to PING (ICMP), wireless gateway considers communication line is
disconnected already, and it will release the original link, then dial-up again
automatically, till communication link is smooth. So please make sure the
selected IP server address is stable and on; otherwise, gateway will be judged
to be off-line, and make gateway on-line and off-line frequently.
Note: The selected destination IP address server is allowed to have PING; if
not allowed, the destination IP address server doesn't respond to PING, and
thus the gateway will be considered to be off-line, and make gateway online
