Accessing My Cisco lab from outside (from the internet)

[ccnproutingandswitching]

Hi ,

Does anyone have an idea about , how can I access my Cisco router from the internet . I can telnet from inside but I can't from outside.

I can ping the router from outside but I can't access it using telnet.

If you are using a public IP you could create a static NAT to translate the private IP to the Public IP and using specific ports like ssh or telnet.

I already did , but still does not work .

Hi

Try to configure something like this static NAT:

ip nat inside source static tcp <private IP> 22 <Public IP> 22
