Advantech BB-SL30210110-XSWH User Manual page 40

Ethernet connection fails or isn't establishing.
It is possible to turn auto negotiation off and set a rate and duplex manually on the
Ethernet interface of the router.
DynDNS doesn't function.
With private APN this is not functional.
If the same IP address is recorded in your canonic name as a dynamically assigned
address, it means that the operator is using NAT or a firewall.
Verify NAT using ping to the static server address.
Verify a Firewall by accessing remotely to the router's Web interface.
The operator may not provide the address of DNS server and without DNS server's
address it is impossible to connect to the dyndns.org server. The following mes-
sages will be shown in the system log:
– DynDNS daemon started
– Error resolving hostname: no such file or directory
– Connect to DynDNS server failed
L2TP or IPSec isn't establishing.
Check the system log for error messages.
I switched the router to offline mode by SMS message, but the router is in online
mode after restart.
SMS messages do not change the router configuration. They remain in effect only
until the router is restarted.
Serial communication is not functional.
Verify that the router supports serial communications. Also verify the serial com-
munication settings. To do so, open the router's configuration menu via the web
browser, select the appropriate expansion port and verify the settings in the config-
uration menu.
