I want to access the CLI over the Internet of my UC520.
Internally I can telnet ot the CLI using Hyperterminal to the default address and port, 192.168.10.1 23
I set up a telnet password and even set up a static nat to between by static public ip and the above address:port. But still no luck.
What am I missing?
ip http server
ip http authentication local
ip http secure-server
ip http path flash:
ip nat inside source list 1 interface FastEthernet0/0 overload
ip nat inside source static tcp 192.168.10.1 23 interface FastEthernet0/0 23
I see. In that case, what you need to do is edit the Access List on the WAN interface to allow for Telnet inbound. Typically this access list is 104.
Do the following:
1) show run int fast 0/0
To get the output of the configuration for the WAN interface. Identify the ACL number (ip access-group XXX in)
2) Then do "show access-list XXX"
3) You will get an output with sequence numbers. This is the order in which the entries are read and the ACL enforced. You will need to insert your "permit" for telnet in the list.
4) You can put is at the top of the list with something like:
ip access-list extended XXX
5 permit tcp any any eq 23
5) Type "exit" and "wr mem" to save.
It is usually better to use SSH to connect from the WAN, it is more secure. Isn't this an option? Also, it is always a good idea to enable the VPN server on the UC500 so you can connect remotely and run CCA (that way you don't have to wait to be on site).
