Cisco 806 for 8 static IP setup

bence8810 · ‎02-26-2007

Hi,

I have obtained this 806 basic router, and I would like to use it for my 8 static IPs at home. This is the first time I am configuring a Cisco router, so it gives me a pretty tough challenge. I basically need it to have my 8 IPs going through. One will land on this device, or maybe 2? Does the internal interface need to be a Static IP, if I want to have static IPs beneath it?

Another IP would be for a different firewall, which connects a portion of my network to a corporate VPN solution. One IP would be for my home WLan router, and some other IPs for Mail, web, etc survers.

How do I go about configuring this? I am unabe to find info, or not searching with the right keywords. This is how my config looks like now, which connects me to my ADSL PPPoE line, but currently doesnt allow me anything else. I cannot even ping addresses outside. You will see that my Eth0 interface is configured for an internal Fake address now, but this isnt my end goal.

Thanks for any help,

Ben

Hi

Thanks, in the meantime I solved with another approach.

I didnt know enough about networks it seems, and I thought if I get one IP of a subnet on the WAN side, I can get the rest on the LAN side by default in the DMZ. As my 8Static IP is just a regular and not professional package it isnt a point-to-point thing, where you have 2 subnets, one on the WAN side, and your real IPs appear on the LAN side.

What I did was I used on my dialer interface the

ip unnumbered ethernet 0

And for the ethernet 0 I added

ip address mystaticip mysubnet

This allows now to have a mirrored IP address from the WAN side to the LAN side, and therefore I am able to use the rest of the IPs on my LAN.

Here is the related configuration that belongs here:

[code]

interface Dialer1

ip unnumbered Ethernet0

[/code]

[code]

interface Ethernet0

ip address xx.xx.xx.65 255.255.255.248

[/code]

Thanks to the nice people at broadband help forums for the solution.

Best,

Ben
