Telnet remotely

[NickAgr68]

Hey everyone, I'd really appreciate some help on this. I'm brand new to networking and I recently setup a new Cisco 2960 switch that I'm trying to access remotely using telnet. I can access the switch over my LAN, on the same network, however, if I go to access it from a remote location, I cannot gain access to the switch anymore.  I know this is probably a basic but I have been searching for days to find an answer to this and really trying to learn.

Just a few more details, I'm trying to do this using Putty. When I go to access my switch using the IP (10.0.1.12) that I assigned it in a remote location (say my brothers house), is that the right process? Am I even going about this the right way? 

Any and all help will be greatly appreciated

Here is how my switch is configured right now:

Hi Nick,

Please share the config of the switch.

Let me check if we are missing something.

Hi Aditya,

Ok great. I'm going to put some x's in for the public key for privacy reasons but you will see it in the config.

Hi Nick,

Do you have a default gateway set ?

Check the output of show ip route on the switch.

Hi Aditya,

Ok, I issued the command "show ip default-gateway" and got a result of 0.0.0.

Switch#show ip default-gateway
0.0.0.0

For the default gateway, should this be setup as the default gateway of my router? For example my router default gateway is 10.0.1.1

Thanks,

Nick

HI Nick,

Try changing it to the next hop ip of the outside.

Hi Aditya,

I issued the command tracert 8.8.8.8 in my command prompt and then set the default gateway to the next hop IP out of my LAN but it did not work. Please let me know if I did this right. 

Just so you see where I got the info from:

How I found the next hop:

Also, I forgot to mention, I can only ping my external IP that I setup on vlan 3 in the command prompt and get a response from it. 

If I ping the external IP that I setup on vlan 3 either in Putty or Teraterm, that is when I get the error messages.

If I ping the IP on vlan 1 (10.0.1.12) I get a result in putty and teraterm.  If I attempt to ping any other IP address in those applications, I get a failed result. That happens on both my LAN and and remote locations.

So what is the difference when you connect from your home and when from the remote location ?

I am unsure, but it has to be because I don't have my switch configured properly to allow me to telnet in unless from my home location where my switch is located.
