Multiple Public Ip Setup

[satanic1]

Well, I am new to TechIMO and here is my first post. My background is mainly in DVD and CD burning and ripping but I also run a small web hosting service. Having this web service for the last 10 years has helped me out alot in keeping my costs for new equipment down.

Recently, I picked up more clients and so I needed to build another server box (W2K). MY ISP assigned me 5 publice IP's many years ago but since I was only using one box to run my services, I didn't need to use the other 4. Now I have a need to use 1 for the new server box and another one for a VPN project I am working on. I assume I will need to upgrade my hardware router in order to accomplish this but I thought I would post here for any suggestions on how to set this up. Here is my current system:

Internet/DSL Box
|
UNIX firewall box
|
Wireless Linksys BEFW11S4 cable/dsl routerw/4 port switch
/ \/ \
W2K DC server | 2 wired / 2 wireless workstations
|
new W2K server

So, here is my question. How do I assign/use another of my static IPA's on the new server? Would I need to upgrade my router to one that would handle multiple public IP's? If so, then any recommendations on which brand to use? If I upgrade then I suppose the new router would have a feature whereby you could assign a public IP to a private IP (server) on a 1 to 1 relationship. The other option I tried and works is to make my new server a member server in active directory and my Linksys directs requests for these websites to the new server with no problem. However, this is still just using 1 IP. I would like to use another IP since my VPN project will probably need it to run correctly and I will be building a new VPN server box for that. I would just like to know how to set this up now when it is not that critical.

Thanks in advance for you help.

can't you hardcode the IP addresses into the computers and turn off the NAT feature of the router?

meese...will repost...thanks

berkelyblue...I gave that a try some time ago and that didn't seem to fix the problem. What I did was to turn off the NAT and harcode the IP's in all 3 boxes (at the time) I had. Yes, I also hardcoded the gateway, dns servers etc. to the external numbers given to me by SBC. That didn't work.

So what I ended up doing was to use a 3rd party pointing service called mydomains.com to keep track of all my customer accounts (domains), and had that service point all of them to my #1 IPA. That worked very good for all these years. Now I need to establish a second box with a diff IPA located on it. So, as you suggested I hardcoded the second box with my second IPA but, since the router is listed with my #1 IPA, it fails to send a request of domain#2 to that box.

So I figured I needed to get another router or switch which is capable of handling multiple public IPA's and then direct those requests to the private IPA's as requested.

Any other suggestions? Thanks again in advance.

You will need to setup virtual interfaces on the Unix box, then forward them to the appropriate box. Having the router also in there is just going to complicate things with little benifit. IPCop supports exactly what you want to do out of the box. http://www.ipcop.org

As far as assigining more than one IP to the windows box, go into TCP/IP properties and do just that. As long as they are all static and have the same gateway its real easy.
