Setting up a DSL connection to access multiple servers

Hi all:

I have a DSL router that includes 6 static IP addresses. I need to set up my
network so I can access 2 servers via the web, one for the internal web site
and one for the public facing web site.
My first question is if I plug a hub into the DSL modem, which only has 1
Ethernet port, and then plug routers into the hub, will the routers be able
to grab static IPs from the ADSL modem via the hub? I'd like to set up
routers so I can then use port forwarding to forward HTTP requests to the
appropriate servers.
I have my server setup with 3 NICs, one is plugged into a router that is on
my internal LAN, and the other 2 I want to connect to the routers. I would
also like to use Virtual Server to run the separate web servers.
I am not sure if I am explaining this correctly, so here's what I am
thinking:

|->Router
1-->Forwards to NIC 1 on the server connected to VM 1
Internet->ADSL Modem->Hub------|
|->Router
2->Forwards to NIC 2 on the server connected to VM 2

So my thinking is that the routers would grab static IPs from the ADSL
modem, I then set up my public DNS records to point domain names at those
static IPs, and then the router port forwards the HTTP requests to the
Virtual Server.

To further confuse myself, I used to have this set up like this:

Internet->Cable Modem->Router->Internal Network with IPs 192.168.1.x, and I
manage servers on this internal network by using remote desktop to connect
to the servers. Since they are all on the same subnet the connections were
never an issue. So the 3rd NIC on the server has an internal IP 192.168.1.94
and is connected to a 3rd router.
If anyone can give me some insight into whether what I am doing will work or
is totally off the wall, I would greatly appreciate it!
John.

If you have a decent DSL router you can do all of that in one hit.

You plug the cable directly into the DSL router. You allocate the pool
of public IP addresses to the router. You don't need to use port forwarding.
You can use address mapping to map specific public IPs to LAN IPs.

If you really want to use your server for this, RRAS can also handle a
pool of public IPs and static mapping. You don't need additional routers.

Hi Bill:

Thanks for your note. That sounds interesting, but I doubt I have a decent
DSL router, it is an Aztech DSL605EU

http://www.aztech.com/prod_adsl_dsl605eu.html

and I am not sure how to "allocated the pool of public IP Addresses to the
router".

RRAS sounds like it could be a good option. Would I plug the router into one
NIC and then another NIC into the HUB and then plug the other computers into
the hub?

John.

You mentioned you have 6 static IPs. However you mention later on that it's
ADSL but didnt' mention SDSL. I am thinking it is SDSL, since I don't
believe or didn't think they do, offer multiple public IPs with ADSL but
rather with SDSL. But later on you mentioned a Cable Modem in your diagram?
My bet is still on SDSL. :-)

Either way, the router link shows it as an "ADSL2+ Ethernet USB Router
Modem" which supports PPPoE, but implies it only supports one external IP.
As Bill said you need a better router that will support this function. I
thought when a service provides multiple public IPs, they also provide a
router that will support it. If this is the case, give customer service a
call to see what's up.

All in all, I would suggest a Cisco PIC 501. It supports multiple public IPs
that you can map publicIP1 port80 to say webserver1 on 192.168.1.10, and
publicIP2 port 80 to webserver2 on 192.168.1.20, etc. Then you can go to
your registrar or whoever hosts DNS for you, and sepecify the additional
www2 or whatever you want tocall it under your external domain name and
provide the new IP. The PIX also gives you many additional features, bells
and whistles that many of these service provided routers do not.

Hi Ace:

Thanks for the note. I am a software developer at heart so I apologize for
the confusing descriptions. The cable modem is what I used to have, now I
have signed up for a service with DSL but I am not sure if it is ADSL or
SDSL. I do know that the service details 6 static IPs so I will try to find
out what's going on there.

Thanks for the recommendation on the router.

John.

I'm sure being a software dev you are very knowledgeable in areas I am not.
That's why we all work together!

I believe it may be SDSL because of the IPs. See if they have a different
router they can offer for you, if not I would actually bag theirs and go
with the PIX. Make sure you get a 3 year support contract. They will even
configure it for you over the phone/remoted in. Their service is pretty
cool.
