Q: I was talking to a buddy who Astaro setup in a similar situation as me, and said I can not walk between my Astaro Internet and a switch and then assign multiple WAN dynamic IP addresses to my internal network computers.
Is this true?
Right now I have
Cableu003e Switchu003e computers own IP and router with a private IP router shares its ip with a few computers that do not need their own external ips
So how can I get a router between the service performed abd-switch, and have to deal with dynamic IP addresses of the service? Seems possible to me, but I havnt tried anything.
If I can do, will Astaro (http://www.astaro.com) let me or do I need a good hardware router?
Re:Thanks for your help, but where did I say I do not need it, as that's the only thing I do need. But hey, it's okay, I figured out what I'm going to do, and I understand-
Re:My advice:
I am sorry, but what you are talking is quite impractical….not so much impractical, but jsut a waste of time.
You stated that you do NOT NEED the multiple IP. YOu did not however state whether or not you are SURE that they are dynamic, and whether or not MAC adressing or hostname checking is involved.
This is what I recommend you do :
1)Set eth0, or whatever your WAN/untrusted connection is, to serve as a DHCP client on that interface
2) Eth1 should be set as a DHCP server with NAT masquarading ON.
3)plug your cable cable into eth0 and your switch into eth1
That's it.
Astaro will recieve a dynamic PUBLIC IP from your ISP and then give your other PCs private IPs throught it.
1) You DO NOT NEED the multiple IPs; you said so yourself.
2) You will have no internet problems. If you need port fowarding, Astaro can provide you with easy port-fowarding.
Re:Ya, I got Astaro running, and now I'm slowly setting it up.
Re:I'm glad you finally clarified the service you have, it makes it soooooooo much easier to analyze a problem when you have the facts.i/expressions/rolleye.gif
I'm trying to figure out if you could use one of the dynamic IP updating services to track your current IP address and somehow use that to solve the problem of the IP addresses changing. I've never used Astaro, but I can see that it may be a solution, given that you have the public IP addresses to work with. It'll be interesting to see if you can get this working. 
Re:Alright. So under Astaro it will have:
:CLIENT:CLIENT:CLIENT:CLIENT:ROUTER(looks like another computer to astaro):
and under Astaro, I'd set the router as DMZ?
It just confused me, because I always thought of DMZ as restricting access to internet to one computer. And If I did that, wouldn't it restrict everything to ROUTER, and no CLIENTS would have access?
OR, do you mean inside my ROUTER, make it DMZ. But then, I want that ROUTER to give access to a handful of computers.
Also, do I just assign same subnet to all computers to network them?

Thank you so much, that's what I imagined and my friend was confusing me, insisting it would not work.
Would you mind taking an extra five minutes and explaining exactly how it will work? If I set it as DHCP it will take IPs from cable company and sort them out to computers? Also, if I disable NAT, will I still be able to network these computers together to share files, printers, ect?
Thanks everyone.
1) NAT is primarily for masquarading IPs, as in hiding them fro mthe public network.
Disabling it will mean that the DHCP server will see all the machines, and assign an alowable amoutn of IPs.
I have to go but I'll finish later.

Oh also, in addition to those four client computers with independent IPs, I'd like to use a single seperate IP for my wireless router, which will be used for computers that don't need this 'feature'.
Yeah…just set it as a DMZ machine so you won't have port issues.

Sorry. I have Comcast Pro (DSL isn't available here). So Comcast gives me 5 dynamic IP address's.
I have four computers which need there own IP address's on the internet. They are not servers, they are just clients, so I don't need static as no one is coming to them, they are just sending requests. Yes, it is not an option for them to share an IP, I wish it was that way.
Sadly, I'm under the impression that Cable only provides dynamic ip's, and that's what I got. They don't change often, so I don't mind manually updating which IP gets assigned to what computer, if it's possible for something to detect the dynamic ip's being assigned.
Does this make more sense? Sorry I'm so vague. Thanks for your time.
Okay.
Set astaro as a DHCP client but disable NAT.
That's it.

Re:I agree with guy in that I don't seem to understand what you need.
Remember that basic cble/dsl service and home networking works this way:
On average, you are regularly ONE assigned a dynamic ip address by your ISP that is unique to the ISP's network. (DHCP). You need to specify exactly how many public IPs you have. ITseems as if you have more than one.
When using a router set to DHCP as well, it gives connected devices on its LAN side dynamic IPs unique to ITS network. Any outgoing traffic([to the web] is masked under the identity of your Public ISP-IP. Basically, it directs traffic troguh a small pinhole, and coordinates the sending/recieving of htat data to the respective device.
Astaro, in your case, should serve two primary puposes:
1) a DHCP client for the Cable network, or PPPoE if you have DSL.
2) It should serve as a DHCP SERVER to your netowrk.
Astaro can do SO much more as well, such as VPN access, traffic shaping, and Stateful Packet-instection, but you have to obviously get the basicas to work first.
Good luck
Re:I still don't understand exactly what you're trying to do. When you speak of "multiple WAN dynamic IP's", what kind of Internet service do you have? If you don't have multiple static public IP addresses, I don't see how you're ever going to do what you're trying to do! AFAIK, you NEED to have those multiple public IP addresses in order to forward them to anything, dynamic IP addresses will do you no good.
This was the kind of information I was fishing for in the first thread, please be specific as to what kind of Internet service you have.
