IP address, NAT.... Need Help :(

Hello,

I am thinking of expanding my business but I only got 5 physically usable IP address and already 4 are used for my webservers.

Is there anyway I could use the Last IP address on a Router or Some form of equipment to allow me to host multiple WebServers ( with HTTP, FTP etc )??

Thanks for your Help

Yes, this should work. Get a router connected to the Internet via a modem and then plug your new servers into this router. On the router, make sure that things like NAT are enabled, then configure port forwarding, so that, for example, all requests on port 80 are forwarded to one server and those on port 21 are forwarded to another computer. You should be able to specify the local IP addresses of the servers which you want to host servers. These should then all be available from the one external Ip address.

couple of ways,
1. setup a reverse proxy server ( one web server proxying, caching and dishing out the web servers behind it).

2. set your web servers or ftp to listen on different ports and use port forwarding on the router. so web server 1 would listen on standard 80 and webserver 2 on port 8080 that way you would have 1 ip hosting two or more web servers ( down fall is that IE defaults to port 80 and all other web/ftp servers on non standard ports would have to have the port after its URL ie.. www.webserver2.com:8080)

So to host them I would get the www.something.com:1234 kind of address?
Because it would be a killer if I need to take another 10 private IP addresses..... and I am looking for a lower costing alternative for this.

There is no way to make them appear like a normal website address?

Thank You for your help

you need to start using name-based virtual hosting. that's more of an apache thing. i have a machine with 5 domains on it, same IP.

Ermm.. What I need is 1 IP, Many Servers and Many more domains
Because I only got 5 IPs and 4 are already used up and I got 1 Spare but I was thinking of getting 10 more servers.....
Having 10 more IP addresses would be very very costly and I am trying to bring down the cost.
( I am not on dedicated hosting or Co-Location. I pull my own lines to the office )

How do DataCenters do it? Surely they can't possibiliy have 1 Public IP address for each and every server that are co-located with them right??

Please advice thanks

I think you miss understood, the first way would be to use a reverse proxy this is how colo's do it. Im sure you know what a proxy server is it make http requests on behalf of the user PCs behind it, a reverse proxy does the opposite being it makes responses to multiple web servers behind it. ( it will retrieve from multiple web servers behind it and cache their web pages in its RAM which makes it faster also) the second way was to use port forwarding. and virtual web servers are not just an apache thing.

Ah what I want to do is how the Co-Lo providers do it. Because I run my own lines here. Port forwarding is good but makes the address look awful....
Any idea how the Co-Lo people do this?

Thanks

AGAIN hehe... I think you miss understood, use a reverse proxy this is how colo's do it! Im sure you know what a proxy server is it make http requests on behalf of the user PCs behind it, a reverse proxy does the opposite being it makes responses to multiple web servers behind it. ( it will retrieve from multiple web servers behind it and cache their web pages in its RAM which makes it faster also) The reverse proxy does not use the different ports!

I see..... I got a router to do the port forwarding

But I don't seen to get it to run..... when I plug into that router all the posts ( other than 88 ) are ll blocked up..... I can't even access the remote control panel....
