DynDNS does not work.
• With private APN this will not work.
• 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.
• 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.
FTP will work on LR240/241 routers only. You can use SFTP on all routers to transfer files to/from the
router. If having troubles with FTP on LR240/241 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)
You can use SSH on all routers or Telnet on LR240/241 routers only. SSH is enabled by default, but
you can verify in Web interface in "Configuration" section, "Services", "SSH". Then connect with any
SSH client on port 22 of the router. User and password is the same as for the Web interface. Telnet
on LR240/241 routers can be enabled here: "Configuration" section, "Services", "Telnet".
