Cisco 2621 Configuration help

[Tegguy92]

First of all please let me admit I am brand new to cisco and am trying my hardest to learn. I have tried searching and been trying stuff for a couple days now but I have a Cisco 2621 router running off a cable modem and I can't seem to be able to get internet access or ping to work. I am unsure about the configuration of the DNS servers. Any help you can offer that would be appreciated. The configuration below is my current config. I do get an IP address when plugged into my modem. One isn't listed now because i'm plugged into my netgear router.Thank You

If that's not doable,

ip route 0.0.0.0 0.0.0.0 f0/0

 

[Tegguy92]

Spoke to the company they won't give statics for anyone other than business customers. According to the person I spoke to a 10.x.x.x address is what the modem gets and there is a problem with my router.

I will try the recommendation when I get home and see if that works. I'm still curious as to why I pull a 10.x.x.x through DHCP on my cisco

 

[Tegguy92]

SweetRevelation I tried that and I still have nothing. When trying to do stuff from my router It will resolve a name to an IP address but it fails the ping. I tried to ping the IP address i'm pulling on f0/0 from the internet and it has 100% failure rate (I don't know if respond to ping is disabled on cisco routers)

on my desktop i'm getting the following
IP: 192.168.1.101
DNS: 192.168.1.100 (I don't know why)
Default gateway: 192.168.1.100
and I can not ping anything or go to any websites

I'm so lost right now

 

[Tegguy92]

Ignore the portion about on my computer I had the wrong cable plugged in here is what I get when actually plugged into my cisco

Ip address: 192.168.1.100
dhcp server: 192.168.1.1
dns server: 65.32.5.111 65.32.5.111 (manually configured on cisco)
default gateway: 192.168.1.1

 

[Tegguy92]

Getting closer I am able to get ping to resolve an IP address but still no response. I'm able to tracert too but I still don't have internet access. I have a feeling i'm forgetting something simple and stupid. Here is the latest config

Can you ping from you computer to the router interface it is connected to? Then can you ping to the external interface?

If you can't ping the external interface then what do you see with a Sho IP Route?

Hang on a minute.....backtrack, You said your Netgear router not cable modem. If the netgear is a router then it is dealing with the Nating to the ISP and sending it in on the 10.54 subnet so to hang your router off that, you wouldn't need to Nat as the netgear is already doing it and you would route to the 10.54 network with a gateway of 10.54.224.1 Your 2600 is a router within your own network rather than between your network and the internet!

 

[SweetRevelation]

Other than removing the second access-list 1 entry, I think your config looks good, it SHOULD work unless I'm missing something major too.

 

[Tegguy92]

Ok let me clarify. When I say netgear I mean my netgear is the only router on the network plugged directly into my modem and my computers are using that to access the internet. When I say Cisco I mean the Cisco router is the only router on the network(netgear is removed) and is plugged into the modem and everything it trying to use that to access the internet

When I have my computer hooked up to the cisco I can ping the external interface just fine I haven't tried to ping the internal interface but I assume it's working.

I've tried removing that second access list but can't seem to get it to go away it should simply be "no access-list 1" correct?

 

[OzzieGeorge]

But is the Netgear routing or not? You say that "my netgear is the only router on the network plugged directly into my modem and my computers are using that to access the internet" then you say "When I say Cisco I mean the Cisco router is the only router on the network(netgear is removed) and is plugged into the modem"

Just what modem are we talking about? The topology here seems to be the first hurdle! What connects to what in each scenario? Try and list each device and what it does!

 

[Tegguy92]

This is a residential cable line so it comes into cable modem then goes to router then to computers.

Currently it is wan -cable modem-netgear router- pc
trying to make it wan - cable modem- cisco 2621 - pc

sh ip route


We must go always forward, not backward
always up, not down and always twirling twirling towards infinity.

 

[Tegguy92]

Cisco_Routersh ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

Gateway of last resort is not set

 

[imbadatthis]

ah ... it doesn't even have its own connected routes ?
thats not right..
did you forget to paste some part of it? have you erased your config?

[Tegguy92]

I have not erased anything since I started this thread and I pasted everything listed. Should I try ip route 0.0.0.0 0.0.0.0 f0/0 again?

 

[OzzieGeorge]

Copy run start

Reboot then check again!

 

[Tegguy92]

Still the exact same

 

[OzzieGeorge]

I've actually had this happen on one of my routers, bad news is I don't know what eventually cured it! Try putting in static routes for everything and see if they appear in the Sh IP Route.

 

[SweetRevelation]

Try finding and loading a new IOS. Your router does not appear to want to route.

The sho ip route being blank is a big one.

 

[Tegguy92]

I've been looking for a way to load a new IOS but I can't seem to find one. Can anyone provide me with some advice? This is my first cisco experience

 

[SweetRevelation]

You can run a tftp server on your laptop, give the router an IP in the same network and transfer it that way.

dir flash:

will show you what's on the router flashcard now, make sure you have space to keep the old IOS and load the new. Check there to see if there maybe is an alternate IOS already on the device.

show ver will show you which IOS you booted from

something like System image file is "flash:c2600xxxxxx.bin"

If you have a file on your flash that's different from that but is also an image c2600 something.bin you can try to boot to that image instead by putting into the config

boot system flash:c2600xxxxxxxx.bin

IF you don't have any alternative images on your flash, and you have space for the one you want to change to, put the new image on your laptop running the tftp server and use the command

copy tftp flash

it'll walk you through identifying the source IP of the tftp server and the name of the image and all that.

Make sure you can ping between the devices before you worry about trying to copy it.
