Cisco 2900 Setup

Cisco / 2900

Specs: Windows XP
Good Morning,

I am trying to set up our new 2900 series router with our new internet connection. I am a bit confused about what setting to apply to the router. I have two sets of IP addresses - our internal ones (servers, DHCP, etc) and also the ones we were provided with (new external IP addresses for internet, mail, etc). I know we will need to set up a NAT, but I am still having trouble getting the router to work using CP express.

Any help would be greatly appreciated as I am completely new to this. Thank you!

From the looks of it, you don't have a lot of experience either configuring a Cisco router, or setting up NAT/DHCP and a network.....or both. In any case, in light of this I highly recommend you hire a qualified professional to set everything up for you. This will likely save you time, money and frustration.

Unfortunately that is not an option. I work at a non-profit, and instead of being consulted on this prior (which I would have advised them to hire someone), they went ahead and this has been dropped on my lap. My only option now is to try to fix this myself.

The DHCP is already set up on our server. My main concern right now is configuring the router between our internet connection and our network. I have a list of all the IP addresses, I just need help figuring out which ones should go where. Using Cisco CP Express I have been able to bypass a lot of the confusing command line configurations.

If no one here can help me, perhaps someone can point me to an online resource that explains how to set up a basic configuration. Thanks in advance.

Sorry to hear that. It may not be too late though. Since it's a non-profit organisation, you might be able to find someone who's willing to donate some time. I have done so in the past and helped setup an office, and it's network, servers, and domain for a non-profit organisation.

I've never used CP Express myself and have done all my work on Cisco products from the CLI.

I can tell you, you'll need to configure an internal IP address on the internal interface. This interface will be your 'default gateway' address for all internal clients requiring external access.

On the external interface of your router, you will configure your TCP/IP settings as given to you by your provider. This will be your external, public address with all associated settings (DG, SM, etc).

Finally, you will have to ensure you have a route set from the internal interface to the external for traffic to get out, and back in. I can't help you much with this. I have a lot of experience configuring Cisco switches, but very little with Cisco routers. We use OpenBSD based routers where I work, ergo my lack in that specific area. I suspect I could figure it out fairly quickly though, but I'd need to be sitting at the console to do it.

I would also highly recommend you put a firewall between the external interface of your router and the external connect (ie: Internet >> Firewall >> Router >> LAN)

As to the exact commands, I can't tell you offhand. If you can't find help, I recommend doing some searches on Cisco's website for your model router and it's associated CLI. You can also google for setup information since you're looking for exact commands. Don't forget, there will likely be some Cisco forums out there where you could ask for help too...again, explain your situation (ie: non-profit org)

I still recommend you make some calls to local consultants and computer businesses. Explain your situation and need for someone with experience with Cisco products to help you. For a person who knows what they're doing, you're looking at less than an hour of their time to configure the router.....maybe even less than 30 minutes.

This problem has not been resolved yet. I keep getting stuck at the same place. I have been using CP Express to configure the LAN and Wan, and after I update the settings, I have not been able to get back into the router. The instructions say to use the new LAN IP in a web browser to access CP Express, but it never works. However, I can ping the router at that IP address. Not sure what I am supposed to do next. Any help would be greatly appreciated!

im afraid the cp express im clueless about i can only use the cli. if you want i can help with this

i think on that device you can set up a firewall. id say make sure your not blocking access if that the case

but from the sounds of it.
try setting everything up but do it with a cross over cable and a pc directly connected. once the settings are applied to the router then change the ip address settings on the pc so the nic is in the same ip range of the router lan and the gateway of the network to be that of the ip address of the router. then give it a go.

can you get into the console connection?

I've never used a crossover in a situation like this. Will it even work? A crossover is only required when connecting like devices. Which is to say, when connecting PC to PC, switch to switch etc.

Router to PC is not a "like" connection.

When setting up any cisco device, including routers, I've always connected with a regular network patch cable and the console cable.

yeah it will work.

the rule for similar devices is correct but its a bit more detailed that that, it is devices that have the same type of port. Since a pc and a router both can have an ip address assigned to the port then a corssover will work since they are the same port type. so they are "like". if it has worked previously for yourself then either the port on the router had autocrossover or a switching module installed and you where conecting through that. oh and inversly a switch chattached to a hub is a cross since the port type is the same.(this last bit has been amended since for some reason i said router instead of switch)

cisco loves to pick this question out of the bag on their tests as it trips people up.
