3.2.13 Ping WAN
Ping WAN function provides you with an option to check the WAN connection is valid or not, if not,
the router will switch from Ethernet to the modem Dialup, or from the modem Dialup(Always on mode)
to Ethernet.
After Ping WAN is enabled, it does not doing the PING all the time, it only happens after finding that
there are data packets going out(to WAN) but none is coming in(form WAN).
Note 1:
When modem Dialup is activated, Ping WAN will take place only for "Always on mode", not for "On demand
mode".
Note 2:
When modem Dialup(Always on mode) is activated and "WAN LInk Timeout = 0", after Ping WAN confirms that
WAN connection is not ok, the modem Dialup will be disconnected and tried to connect again, it will not switch to
Ethernet.
Note 3:
The
Ping WAN packet is transmitted from current activated WAN interface to the assigned IP, such as from
Ethernet or the modem Dialup, it can not transmit from both Ethernet and the modem Dialup simultaneously, so when the
modem Dialup is activated, only after failure of Ping WAN (Always on mode), idle timeout or max connection timeout(On
demand mode), the router will switch from the modem Dialup to Ethernet.
