• You can verify NAT using ping to your server with static address and then compare with router's
IP address.
• You can 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 messages 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 is not establishing.
Check the "System Log" page for error messages.
IPSec tunnel establishes but the communication does not run.
Probably there are bad routing rules defined in the connected devices, or the default gateway.
I switched the router to offline mode by SMS message, but the router is in online mode after
reboot.
SMS messages do not change the router configuration. They remain in effect only until the router is
rebooted.
Serial communication is not working.
Verify that the router model supports serial communications. Also verify the serial communication
settings. To do so, open the router's configuration menu via the web browser, select the appropriate
"Expansion Port" from "Configuration" part of the menu and verify the settings.
Is the router Cisco compatible? Can I use the Cisco configuration?
No, the Firmware in the router (Conel OS) is based on Linux with BusyBox. Thus, the Cisco
configuration cannot be used. But network connections are defined by standards so connecting the
router to the Cisco or other networking devices is possible and will be compatible.
FTP or SFTP does not work.
You can use SFTP on all routers to transfer files to/from the router. If having troubles with FTP on
LR140 routers, make sure you have FTP enabled: "Configuration" section, "Services", "FTP". Then
you can connect with any client on port 21 with name and password same as for the Web interface.
If having troubles with SFTP, make sure you have SSH enabled: "Configuration" section, "Services",
"SSH". Then you can connect with any client on port 22 with name and password same as for the
Web interface.
How can I connect to the router's command line? (SSH, Telnet)
SSH or Telnet can be used on all routers. SSH should be activated by default, but you can check this
on the web interface in the "Configuration", "Services", "SSH" section. Then, connect to an SSH
client of your choice via Port 22 of the router. The username and password are the same as for the
web interface. Telnet can be activated here: "Configuration", "Services", "Telnet" section.
