Nortel Business Secure Router 252 Configuration — Advanced
TFTP and FTP over WAN Management Limitations
TFTP, FTP and Telnet over WAN do not work when:
•
You disable Telnet service in menu 24.11.
•
You apply a filter in menu 3.1 (LAN) or in menu 11.1.4 (WAN) to block
Telnet service.
•
The IP address in the
Secured Client IP
field in menu 24.11 does not match
the client IP. If it does not match, the Business Secure Router disconnects the
Telnet session immediately.
•
You are running an SMT console session.
Backup configuration using TFTP
The Business Secure Router supports the uploading and downloading of the
firmware and the configuration file using TFTP (Trivial File Transfer Protocol)
over LAN. Nortel does not recommend using TFTP over WAN, although it can
work.
To use TFTP, your computer must have both Telnet and TFTP clients. To back up
the configuration file, follow the procedure shown next.
1
Use Telnet from your computer to connect to the Business Secure Router and
log on. Because TFTP does not have any security checks, the Business Secure
Router records the IP address of the Telnet client and accepts TFTP requests
only from this address.
2
Put the SMT in command interpreter (CI) mode by entering 8 in
Menu 24 –
System Maintenance
.
3
Enter command “sys stdio 0” to disable the SMT timeout, so the TFTP
transfer is not interrupted. Enter command “sys stdio 5” to restore the
five-minute SMT timeout (default) after the file transfer is complete.
Initial Remote Directory
Specify the default remote directory (path).
Initial Local Directory
Specify the default local directory (path).
