Configure for multiple public IP
I have assigned 8 public IP addresses.
I have two (simple) routers.
What I would like to do is to assign these IP's to different parts of a network infrastructure.
Example:
- one room with IP 1
- second room with IP 2
- ....
Now I use only one IP and one router.
How can I setup what I need?
Right now each room is connected to a patch panel, from patch panel to switch and from switch to router and from router to ADSL modem.
Thanks!

hm.. I am not realy at the location but I think one router is some planet and the other one is some netgear (both are some cheap ones).
Similar configuration was setup at our previous location, but now the office moved.
I didn't configure it before but I assume that if it worked before it should work now too, only I am not such a network expert, but I think it shouldn't be something hard.
I have CIDR 29 which means 8 public IP's.
The ISP said they enabled network of 8 IP's on a given (our current) first IP (a.b.c.104).
They gave me a cidr of a.b.c.96/29
So the range will then be: a.b.c.96 - a.b.c.103

I guess it could go something like this:
1. setup first router (behind adsl) to be a.b.c.104
2. setup second router (behind first one) to be a.b.c.96
3. setup any additional router (behind first one) to be a.b.c.96 - 103
Would this work?!

Yes thats the correct way

Cool :-)
Can you tell me what happens with IP a.b.c.104?
How this works behind the scenes?
ISP routes all assigned IP's to the a.b.c.104? and then? where are other IP's stashed away in a mean time?

I have little problems making this work.
I have ADSL line with original PPPoE access with login and static IP.
This is working ok.
ADSL modem -> Router WAN (a.b.c.104) -> switch
Now I want to make something like this:
ADSL modem -> Router WAN (a.b.c.104) -> Router 1 (a.b.c.96)
-> Router 2 (a.b.c.97)
I assume this is the right way to go.
How do I configure Router 1 and 2? As first one? with PPPoE login? what is the gateway? private or public address? and subnetmasks?
uf... thought it would be easier.

Using ADSL -> switch -> router's will require each router to be PPPoE configured with login information? I assume.
But I would something like, the front router only does PPPoE access with NAT one to one?
Other routers behind it are setup with a static ip (as provided) with gateway address of front router.

did you read all the articles

I'm not sure if there's a good way to do what he wanted but it's easy with a PIX 501 or the like, he did quit posting after mine but you could split the points.

Hi all,
Sorry for not being around this question for a long time.
I don't mind about points being splitted to all posters. PIX was not really an option since I did have few cheap routers I had to use. Final solution was as I thought from the beginning, just wasn't sure on how to set it up.
I think most fair is to split points along all posters since they all contributed their efford and time.
Thanks again,
Peter
