-
L2TP or IPSec isn’t 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.
-
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 pos-
sible and will be compatible.
-
FTP or SFTP does not work
•
FTP will work on v2 routers only. You can use SFTP on all routers to transfer files
to/from the router. If having troubles with FTP on v2 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 v2 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 pass-
word is the same as for the Web interface. Telnet on v2 routers can be enabled
here: "Configuration" section, "Services", "Telnet".
