Question
Second public IP for a new network on existing infrastructure - add new switch or recable?
I have an existing network of servers running in a particular server room. From a socket on the wall we have a single CAT5e cable running into the FE0/WAN interface of our Cisco 1800 series router. A CAT5e cable runs from the FE1 interface on the router into an unmanaged HP 24x100/1000 switch. Our servers are connected to the unmanaged HP 24x100/1000 switch. The Cisco 1800 router is performing NAT. The Cisco 1800 routere's FE0 interface is configured with our WAN static IP, and this is accessible from the internet. Everything works just fine at present.
We are adding a second set of servers into the same room. They will be operating behind a completely different public IP address on a different subnet. Traffic for that IP address will be coming down the existing/same cable from the wall socket. The new/second network of servers will be on a separate local subnet.
If we will have two separate local networks, my understanding is that we need to add an additional switch. So a cable runs from the wall socket into a new switch. A cable runs from the new switch to our existing Cisco 1800, and another cable runs from the new switch to our new router for the new network. That way traffic for both public/wan IP addresses can get to their respective routers from the wall socket.
So if a new switch is required, then can we re-use the existing HP 24x100/1000 unmanaged switch? Thus;
A cable runs from the wall socket into the HP switch.
A cable runs from the HP switch into the FE0/WAN interface of the Cisco 1800.
A cable runs from the FE1/LAN interface of the Cisco 1800 into the HP switch.
A cable runs from the HP switch into the WAN interface of our new router.
A cable runs from the LAN interface of our new router into the HP switch.
All servers are connected to the HP switch.
Thus all traffic is distributed via the same switch on multiple subnets. Would this work, or would it be better to separate out the traffic first via a switch, or is there a better way of doing this?

Everything into the one switch
First Image: This is the existing network as it is right now. Cisco 1800 router is performing NAT.
Second Image: This is the existing network, with the new network shown too. Traffic from the wall enters a switch. The switch sends the traffic to one of two routers depending on the destination IP. The existing network works as in the first image. The new/second network is at the bottom, and will probably mirror the first network.
Third Image: Ultimately providing the same functionality as the second image, but without the use of an additional switch. Thus the one/single switch is doing all of the work.
Hi Praveen,
Thanks for your comments. We're in Ireland. We haven't been provided with the second IP address yet - I expect that to happen at some stage later today. When I asked how the traffic will be delivered I was told it will be down the same cable as our existing traffic, but perhaps they will put it onto two separate cables - I don't know yet.
Hi,
Actually i am in india its my time to go home. i am just attaching a suggestion.
On monday i will give you some more suggestion.
I am assumin your getting ethernet based ISP connection then u need not to use switch at all to connect from service provider to your router.
Directly connect to routers from there if you have Managed or Unmaged no much difference untill your running on different network .
I think its confusing just sec i will make diagram for it.
Regards,
Praveen

Hi,
does your network looks like this , have you configured public ips in servers or only private ips as you have told your router is doing nating, i understand that you want to expose other servers example 10.10.10.x series into different public ip add and you will do nating. I am bit confused .
can you explain me.
Regards,
Praveen
