Advantech B+B SmartWorx LR77 v2 User Manual page 39

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 dynamically assigned
address, it means that the operator is using NAT or firewall.
Verify NAT using ping to the static server address.
Verify Firewall accessing remotely to the router's Web interface.
The operator may not provide the address of DNS server and without DNS server's
adress it is impossible to connect to the dyndns.org server. There will be these
messages 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.
FTP doesn't function.
Router doesn't support active FTP mode. It supports passive mode only.
RS232 doesn't function.
Verify that the router supports RS232 communications. Also verify the RS232 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.
