Redistribution EIGRP, OSPF, and RIP

I am pursuing to get my Cisco certification and mainly I use GNS3 for my lab study. Unfortunately it didn't go as smooth as I expected due to its requirement of memory that drainage the PC's resource. Finally, I decided to buy my own racks for my lab study and telnet it out using secureCRT which I really enjoy it. But there is something else that I want to extend my lab that able to connect my home rack to the outside internet and I think that might be possible but I need to make sure the right topology and configuration. Will anyone have suggestion on my plan? Thank you in advance of your generosity.

Redistribution EIGRP, OSPF, and RIP

Hello,

On my lab setup I am running OSPF between my vlans with my routers. They are connected via layer 2 switches.

On the internet facing router ( He knows via OSPF how to get into all the other devices) I can NAT the rest of the hosts.

Lets say available public ip address is 60.60.60.60 and you have on your rack 2 routers and two switches ( 192.168.1.2, 192.168.1.3,192.1168.1.4,192.168.1.5)

ip nat inside source static tcp 192.168.1.2 23 60.60.60.60 2322

ip nat inside source static tcp 192.168.1.3 23 60.60.60.60 2323

ip nat inside source static tcp 192.168.1.4 23 60.60.60.60 2324

ip nat inside source static tcp 192.168.1.5 23 60.60.60.60 2325

In this case if you from the outside try to telnet 60.60.60.60 on port 2322 you will be re-directed to 192.168.1.2.

This is how I did it!

Hello Arifdatau,

I have a rack also at my place and yes you can access it as long as you have a public ip address available for your equipment. From there you can start doing some nat for the different devices you have in your rack on the border router.

That should do it!

Hi Julio,

I thought so..do you have it setup in your current topology? Yes I do have a public ip, would you mind sharing the configuration that you have now? or if you may have a link somewhere that I could try to implement would appreciated.
