| Subject | Using a public IP-address in my home private network? |
| Message-ID | <84831e41-0f1d-43b3-8d31-00c92a8d7efe@googlegroups.com> |
Hi!
This is probably a simple/easy question to answer, the question is, how do I add a public IP-address to a private network?
Lets say I have 2 computers in a home network connected to a switch, and then the switch is connected to a router.
One of the computers is configured with a private IP-address (10.10.10.10) in the same subnet as the router (10.10.10.11).
The outside interface of the router has IP-address 20.20.20.20.
The second computer should be configured with an external IP-address (30.30.30.30).
How do I set the network up in the easiest/best way?
Is the following setup a valid configuration of my network?
comptuer1(10.10.10.11) - switch - 10.10.10.11(router)20.20.20.20 - internet
|
computer2(30.30.30.30) ----
If it is, then I guess all I need to do on computer2 is to add a default route to 10.10.10.11?
I.e.
#route add 10.10.10.11/32 dev eth0
#route add default gw 10.10.10.11
Or how do you add an external IP-address to a private network?

Depends on your router. In my case I told the router what ports I want forwarded to what LAN ip. If you did that change computer2 to 10.10.10.30. Then if you were at work you could get into computer2 with a ssh some_user@194.237.142.7 Want to see your web page on computer2, just put 194.237.142.7 in your browser url box. Pretty simple.

The problem is how in the world does the outside world know where to send packets addressed to the public IP? It has no idea where it is located. The problem is not with you sending out packets, but them sending them to you. Now, you could somehow get the owner of the subnet on which that computer is located to somehow set up their routing tables to get those packets to you, but the usual way (sending out arp request packets-- what MAC address owns this IP address) will nto work, since you are not on the subnet to which they send arp requests. Ie, you are going to have to get together with whoever actually owns 30.30.30.30 and negotiate with them how to get packets to you. > > Brs

From what you have indicated so far. pretty simple. You bought 30.30.30.30 from some internet provider. With it you provided them with a domain name, say, darkstar.com and you tell friends and family about it. They put darkstar.com in their browser, it asks the DNS server to get an ip address for darkstar.com. A dns server resolves it to 30.30.30.30, browser sends out packets. They get routed to your provider who accepts the packets and forwards them to your router. Your router is set up to accept 30.30.30.30 packets and passes them to your system. A this point, it depends on your router's configuration and how/where you have connected the pc to the router. Assuming a fairly decent isp provided home use router, you would tell the router's firewall to NAT whatever you want open to the WAN to passed to the target LAN pc (computer2) who's LAN ip address is x.x.x.x.

Then you would tell the router only one thing: that the following addresses are in fact externally valid, and not top use NAT on them. So the routing is like this. ISP 'owns' the block of public IP addresses of which they normally hand pout just one, for your router. In this case they hand out - say - 4. IP packets to those addresses come to your ISP because it 'owns' them. Never mind how. ISP 'knows' they are for you, and sends them to your router. Your router has to be 'told' that they are on the ethernet. So it will forward them there., In the reverse direction you probably set up a default route on the boxes using those IP addresses to forward packets to the router. The router will need an additional IP address that corresponds to that network. I suspect that may well be an 'illegal' one, because frankly it is never used by anyone except the router and the boxes.. * The router is then told that these addresses need not be translated, so it sends them out as they are. With no modification of the source address (NAT). * this is the only bit I am not totally clear about > Or is there some other way to solve this? > Since you haven't said what the actual problem is, its hard to say :-) The normal way to make box inside a NAT setup accessible is to still use NAT but accept incoming packets on specific ports and forward them to a specific machine on the internal network, that allows you tyo have one web server, one FTP server, one telnet server etc etc that are globally accessible on the IP address used by your router. But not more than one session per port is possible. The other way is to get that block of IP addresses from your ISP and tell the router that you have them. It should sort the rest out automagically. The bigger problem is that on the cheaper routers how to do this is poorly documented and often badly implemented, because so few people actually do this, its not worth spending time on it when it represents 1% of sales or less. People setting this sort of stuff up are likley to go upmarket for a SOHO or small business router anyway. -- Ineptocracy (in-ep-toc’-ra-cy) – a system of government where the least capable to lead are elected by the least capable of producing, and where the members of society least likely to sustain themselves or succeed, are rewarded with goods and services paid for by the confiscated wealth of a diminishing number of producers.

If someone on the internet wants to connect to computer2 then the packets will arrive using the ip address you have leased from Telefonaktiebolaget LM Ericsson. That address will be 194.237.142.7 or in the range 194.237.142.0 - 194.237.142.255 > The problem to solve is to find the easiest way/setup to have a > public IP-address inside my private network. Again, a "public ip address" is not going let anyone connect to computer2 unless they use setnip01.ericsson.net or 194.237.142.7 You can get a domain from some domain vendor like darkstar.com, but you will have to provide them with your ip address 194.237.142.7

It does require cooperation from the ISP, and the OP’s ISP may or may not offer that service to domestic customers (some do, some don’t), but as a general statement it is technically possible.

The "misapprehension" that I have is the original post indicating 2 computers connected to one router and the desire to have computer2 to have a public ip address other than the _public_ one assigned to his router. "public ip address" being the operative description leading me to the conclusion the OP wants anyone on the Internet to be able to use it to make a connection from their machine to computer2.

Are you using IPv4 or IPv6? Is the router configured to use Network
Address Translation ("NAT") so that a single public IP number is shared by
all the computers on your private network, with your own router allocating
the local IP numbers?
How many public IP numbers has your ISP allocated to you? How many
seperate internet connections have you got?

What is the switch for, if you have a router?

So far, so good; that is a typical IPv4 NAT router configuration. Those IP
numbers are in one of the groups reserved for private local use.
> The outside interface of the router has IP-address 20.20.20.20.
In that case you are working for for Computer Sciences Corporation in
Virginia or Louisiana and really should be asking your IT department for
help. Or not be doing whatever it is you're trying to do.

First, get the IP addresses you need from an ISP.

Now now. 20.20.20.20 is clearly a fake.
At least a smiley would have been appropriate in your post.
