Remote Access to home lab?

[namesrhard2pick]

Hello Everyone,

I would like to connect to my home lab from anywhere I have internet access to practice. Could use some tips on how to integrate a 2509 with my cable provider.

Thanks.

Forward port 23 on your router to port 23 of the ip address of the term server.

Please expand on your recommendation. Not clear on what this means.

You should have a cable modem, and if you have more than one computer you have that connected to a router. In that router you forward port 23 which is the port telnet uses to port 23 on your 2509. Additionally you could forward port 9000 or some other random port to port 23

Got it. Will I need a public static IP address that I will telnet to from a remote location, say my office network?

DDNS would be a better solution than getting a static IP. Most ISP's will usually charge you a monthly fee for a static IP. Do a little research and you can find free DDNS services.

A far as the remote access goes. You would be a lot more secure to implement SSH (port 22). The command syntax to implement SSH will look something like this:

Router(config)# crypto key generate rsa
Router(config)# line vty 0 4
Router(config-line)# transport input ssh
Router(config-line)# exit

To enhance security even more, you can create a access-list and apply it to the outside interface.

For ssh, you will also need
router(config)#ip domain-name local

I am currently getting my ip address via DHCP from my ISP. I am having difficulty understanding how I will telnet to my home lab from my office network if I won't know what IP address is picked up? Somebody slap.....

i'm not sure if this is the case for everyone, but i've had my cable connection for two years and an ADSL for the last four years before that. in that time i've actually had an IP address change twice. once when I moved on the ADSL, and once when i changed over to Cable =) addressing is also done through DHCP, but it just seems to renew the current that its using. What specifically are you trying to access. example, i've got a vnc port opened on my home access so i can access my home computer from work for testing things on our public side.

I would like to access my cisco home lab from my office or wherever there is internet access. This is a nice to have for practicing etc. I have currently have Cox Communications as my ISP with a Linksys broadband router. I do get my IP assigned via DHCP. I have one home pc connected to the Linksys router. I would like to connect my 2509 somehow and be able to access remotely. Much like one would access a paid POD of routers/switches. I created an account on DYNDNS as burt suggested but I have run into some challenges. I suspect my ISP is blocking many if not all the common ports. I am not certain where to go from here.

Thanks...

What all do you have in your lab? Just the 2509? If that's the case, just get Packet Tracer 4.01 from Cisco (free). It does more than just a single 2509...

I have the following:

(1) 2509
(1) 2621
(2) 2503
(1) 2501
(2) 2950
(1) 1900

The 2509 is my AS (tired of moving the console cable around).

 

[burtsbees]

Why not just telnet from one to another?
You can set the 2621 up with ssh, and forward port 22 in the LinkSys.

This is not a problem. I would like to access this lab environment from my employers network during my lunch and breaks. It's not critical just a nice to have.

 

[burtsbees]

I agree---why can't you do it like I just indicated? I don't understand the confusion...
