Multiple public Static IP addresses

[ms526]

Hi,

I have been assigned 8 static IP addresses by my ISP, but I'm unsure how to set them up. I'm no newbie to networking, but I've not done this before. The information sent to me by my ISP is as follows:

Router IP address: 87.127.54.*
No NAT IP range: 87.127.54.* to 87.127.54.*
Netmask: 255.255.255.248

I have a Zyxel Prestige 660H router for my connection and have tried to use full feature NAT without success. I would like to give a public IP to my webserver and my desktop which both have private IPs of 192.168.1.4 and 192.168.1.5 respectively. Please could someone advise me how to configure this.

Thanks.

actually you need to find out what is the exact ip address of the default gateway provided from the isp. You mention 8 ip address, but only 5 will be usable.
1 for the network address
1 for the broadcast address
1 for the default gateway
5 usable ip address.

There is seldom a need for more that one public IP address at a site. The normal procedure is to use Network Address Translation and have your router forward required ports to the appropriate computer.

Using public IP addresses on computers when you don't know exactly what you are doing can be risky. I suggest taking a second look at why you couldn't get Port Forwarding to work on your router. It certainly DOES work on other home-grade and business-grade routers.

 

[ms526]

I'm quite aware that port-forwarding works. I used it up until now for my server, but now I need more as I would like to add more servers etc. I'm just looking for someone who can give me an idea of how to configure this.

 

[spidey07]

just setup the NAT for the public IPs on your router.

I'm not familiar with that router, but the manual should have information.

example:
external IP 1 <---> 192.168.1.4
external IP 2 <---> 192.168.1.5
and so on.

You'll have to be very diligent about security and you should probably put access lists/securit on your router to only allow the ports you want through for each particular external IP.

In most case multiple external ISP do not provide you with extra Bandwidth.

I.e. If your contract is for (example) 10Mb/sec., you would get 10Mb/sec. from 1 or 2 or 10.

So unless you have a very specific Topology reason to use more than One, then let Go.

:sun:

Are you guys dense or something? If I want multiple IP addresses, then I'll have multiple addresses and will not be told by a bunch of AOL user retards that I don't need it. I'm aware that I don't get extra speed you fool, I've already mentioned it's because I need to give a unique external address to each host. Is that a problem for you?

 

[spidey07]

No it's not a problem.

There is just hardly ever a reason it is needed.

The AT networking forum is full of very sharp people happy to help, as long as you don't call them retards.

So go and RTFM noob.

Agreed.

And to think I was actually downloading the manual right now to do the reading for you....

I don't mind being called a retard. But to be called an AOL user....That's too much.

I think you just blew any chance of getting help in this forum with an attitude like that. Secondly, since you really don't feel like doing much research yourself to find out why it's a bad idea to not use public IP's other than for use with your router and only use port forwarding to each of your servers then why should anyone give you assistance in this. As spidey said, RTFM.

Fair enough, I was a little short with you. But you must understand that I am not asking if I should have multiple IP addresses or not I am asking how to configure it. I already have my own subnet of IPs and just need to configure it now. Not a single person on Earth could dissuade me from this path I have chosen, least of all some people on a forum. So please don't try.

Also, I have read the manual, both the quick start guide and the PDF off Zyxel's site. It said that I needed to use "full feature" NAT to do this, which I configured correctly, but it still didn't work.

However, when I disabled NAT completely and configured the NIC on my PC to use one of my public IPs it worked, but it was too insecure and seemed odd. I'd like to be able to do this with the "full feature" (one-to-one) NAT as described in their manual, but it doesn't work.

Please help guys, I didn't mean anything by my comments earlier.

I'm constantly amazed by folks who ask for FREE EXPERT ADVICE, and then insult the advice-givers. You are welcome to pay me my normal consulting fee. And THEN insult me.

Are you SURE that your NAT router isn't working properly? You aren't trying to test it from INSIDE your network are you? You need to test it from an IP OUTSIDE of your network.

Right now I'm willing to second that vote.

scroll back up...you need a 1 to 1 NAT for some machines, and a 1 to many NAT for everything else...about 10 lines of config on a cisco router, so I can' help you

Yes. I'm assigning one-to-one NAT to my desktop to test, for example I'm assigning my internal address of 192.168.1.6 to the external 87.127.54.98, and then I check to see If my PC is using that IP by trying going to whatismyip.com or something. When I do this, It either completely loses internet connectivity, or just uses the router IP as usual.

If you look at page 218 at example 3 in the manual from:

ftp://ftp.zyxel.com/P660H-61/document/P660H-61_v3-40(QT)_UsersGuide.pdf

That is what I have done in Telnet, But it just isn't working. I've double checked everything and I swear I'm doing everything right.

 

[ms526]

Bump. Someone please help me with this.

 

[ms526]

Bump 2. Please will someone help me here, I'm really sorry for what I said earlier, I just need some advice on this.

 

[nweaver]

RTFM...do you need to load that config, or reboot, or anything to apply that config?

I may be wrong here, but when using Apache's virtualhost directive is used to host multiple sites, you run into a problem when you attempt to host multiple secure sites over port 443 that only one site can be configured to use that port, so for example if you have site a located at https://a.com and site b at http://b.com and site a has 443 in your httpd.conf, then if you connect to https://b.com you will be given site A's ssl certificate and forwarded to that site this was confirmed by our colo guys (I've never had to host this many domains on a single box before, so I've never run into this issue) and they issued additional ip addresses (of course we run Linux so aliasing those to eht0 was extremely easy) So I don't think that it is entirely true that NAt'ing will solve almost every problem and that no user should need more than 1 public IP address. That being said you catch more flies with honey than vinegar, so insulting us won't make us want to help you heh.
