My company has recently purchased a Cisco 1811w security router, and the responsibility of getting it up and running (and getting a new network scheme up and running for that matter) has been placed in my lap. While I did take a few networking classes in college, I'm a software engineer by trade and the whole Cisco router configuration is a whole new world.
My requirements are to set the router up to allow for 2 private networks (i.e. 10.10.10.0 and 10.10.20.0). The 2 networks need to be able to communicate with each other on a restricted level, such as nodes on 10.10.20.0 can only access 2 specific hosts on 10.10.10.0 and visa versa. Remote VPN is also a requirement, so that employees from home can access their work computers.
I know there is a lot of documentation on Cisco's website explaining how to do this, but it's getting difficult sifting through all of it to get what I need.
Can anyone offer some direction, such as specific documents I should read, and/or specific network setup/configurations I need to put in place to meet the above requirements.
Re: Need some direction setting up new Cisco router.
Do you have a layer 3 switch that you're connecting the router to?
1. Do you know how to get into the router?
2. Will you be using NAT?
3. Do you have public addresses for your internet connection, or are they being assigned?
4. What kind of internet connection do you have?
Concerning the switches: We do have several switches. I don't know if they are layer 3, or how I would even tell. Off the router I do plan on having 2 main switches (1 for each network). Branching off from the 2 main switches will be several other switches, pc's, printers etc. (the standard stuff).
1. Yes, I do know how to get into the router, and currently I have set up 2 VLAN's, one for 10.10.10.0 and the other for 10.10.20.0; and I have the 2 networks talking to each other. Is this a good setup or no?
2. I won't be having any routers behind the Cisco 1811, so I don't think I will be needing any internal NAT, but I'm not sure.
3. We do have public static IP addresses, 10 of them to be exact. We basically have 2 departments at the company. Each department has their own modem/router with 5 static IPs coming in. The plan is to have these 2 modems directed to the Cisco 1811, one pluging into FE0 and the other into FE1 on the back of the 1811. Then network 10.10.10.0 will have access to the 5 IP's through FE0, and network 10.10.20.0 will have access to the 5 IP's throuch FE1.
