Using Private IP to Simulate ISP - unable to ping WAN IP`s

wilder7bc · ‎06-22-2012

Hi I have a home lab network that is connected to my internet. I basically have a linksys router connected to cable modem and in order for my families internet to not go down while testing and learning my CCNA I am trying to treat the Linksys as the ISP.

1. Plugged my 891W router via FASTETHERNET 8 (192.168.1.10) into LAN Switch port 1 of my Linksys E4200 home router(192.168.1.1).

2. I plugged my 891W Gigabit 0 (10.10.10.1) LAN side into my 2950 Catalyst Switch (10.10.10.5 - VLAN 1)

3. my 2950 Catalyst switch (10.10.10.5 - Vlan 1) is plugged into my 2600 series router via the routers FE port (10.10.10.2).

There is a few more routers connected behind r2 but I am not dealing with them right now and there is also a switch connected into s1 but its not being used for this.

891w is labled r1

2950 is labled s1

2600 is labeled r2

I am running RIP Verison 2 for my network protocol.

I can ping all over my homelab everything I can reach as long as I have a protocol up but I cannot reach the WAN IPs. I watched video by Jeremy Ciorara and I tried to follow the wan and nat part from a website http://www.networkstraining.com/basic-cisco-800-router-configuration-for-internet-access/

And none of its working. I am not sure if this is a case where a private IP cannot function as a ISP and I am breaking some rule thats not mentioned in CCNA studies or if its something else.

I tried these commands from Jeremy Video:

r1(config)#ip access-list standard "NAT_ADDRESSES"

r1(config-std-nacl)#permit any

r1(config)ip nat inside source list NAT_ADDRESSES interface fastEthernet 8 overload

However they did not work it was pretty close to whats in the basic website up there I listed as well.

I think I went back to the basic configuration in the config file post above. Its really frustrating as I follow directions and they do not seem to work. I understand I am using my private 192.168.1.0 subnet as an ISP and maybe that has something to do with it but when yoru first learning and things dont work its kind of overwelming as you have problems seeing the big picture and dont yet trust in things you have learned as they are unfamiliar so its easy to get lost.

Anyway any asistance would be great. I will also keep trying to figure this out but so far I have only came up with non working ideas.

Thanks,

Brian

you are not getting any default route on R2.
