I have got about 15 laptop/desktops, file server/print servers etc on a
100mb Ethernet. I have SAR 725 router to share my ADSL connection using NATS
at the moment.

I am wanting to change ISP to one that would give me about 5 static IP
address so I can use a few of the pcs with direct access to the net and for
a couple of VOIP phones.

I have been studying for the .NET+ for a long time, and not getting anywhere
fast due to lack of time and motivation. I have read through most of the
books I have but nothing gives me a clue about this.

I am wanting 1 desktop, 2 laptop, 3 VOIP phones to have there own IP address
so they are view able from out side LAN. I still want the PC's to have
access to everything on the inside of the LAN, especially the servers. I am
wanting all the other and anymore pcs we connect to the network to work
though the nats and access everything on the inside of the LAN as well.

Does any body have an idea of how this would work, or ma I asking the
impossible.

Well done to anybody and understand this,

and a BIG THANKS!!! for anybody who can help me out.

I'll take a crack at this. If anyone thinks it won't work, speak up.

Connect your high speed line along with your VOIP phones, desktop, laptop
and NAT router WAN connection all to a hub.

Create a static route in your NAT router so the 192.168.1.0 network is all
routed out the LAN connection.

In your Desktop and Laptop, create a secondary route (besides the default
route) that would route the 192.168.1.0 network to your NAT router ISP
assigned IP Address as it's gateway.

From your Desktop and laptop, all your internet traffic will be routed to
your default ISP gateway. Any LAN traffic (192.168.1.0 network) will be
routed to the NAT router.

Also when PC's on the LAN want to talk to the PC's out of the LAN, you could
set up static host routes on the NAT router so it wouldn't have to go
through the ISP gateway first.

As far as your VOIP phones go, I'm not sure.

good luck

Windows 2000 Server can use NAT in rras to do this , but that is an
expensive proposition. Your ISP could also provide a soho device - check
their prices, but again it will not be cheap. Here is what you could do. Get
a muliport switch that you will connect directly to the ADSL model. Connect
your router to it and let it use its' NAT to serve computers on the internal
network as it currently does. On the computers that you want to have their
own public tcp/ip address, you will need to put a second nic in each of them
to connect to the switch that will connect to the ADSL modem. Configure the
second nics in those computers to have the tcp/ip address, subnet mask, dns
servers, and default gateway that your ISP tells you to use for those static
addresses. Leave the existing nics in those computers connected as is to
the internal lan except you will need to give them static tcp/ip addresses
for the internal lan (192.168.xxx.xxx). The reason you need to give them
static addresses is that you do not want them to have a default gateway
configured there (you do not have to configure dns server there either).
Windows can only use one default gateway at a time. Be SURE to disable file
and print sharing, and disable netbios over tcp/ip on the external nics!
Then be sure to install a personal firewall on each of the computers exposed
to the internet and configure them for your needs using a default block
everything from the wan rule and then create the exceptions. If at all
possible use a firewall that has intrusion detection and can block unused
outgoing ports also to protect against a trojan horse, etc. After you
configure your computers I highly recommend you port scan your external
addresses to see if you are as secure as you think you are. Good luck. ---

How important is it that you access the three systems from outside the
of your LAN. Unless you make some major bucks I don't see this being
affordable just for fun. If static IP addresses are provided in your area
your going to have to pay for 3 separate accounts. The only static
connections in my area are ISDN and T1s. So for even a cheap $40 monthly
cable connection you would have to pay $120 a month and create a possible
security problem.

I guess I'm just jealous. Let me know how it goes. Good luck.

Getting the IP's from an ISP is no problem and is going to be cheaper with
them. I am currently paying £27.00 +vat and will be paying £26.50 +vat and I
get 6 static ip addresses. Changing from BT to Abel.

Thanks for all your help guys. Just waiting till bt give me a cut of date
and get the able up and running. will let you know how I have gone on.

Have purchased a BIG internet router from solwise, after a few problems in
setting it up, everything is fine.

My set up is:
SAR 715 ADSL router/modem --------- public pc's with an ip for the -
BIG router which has the main network behind it.

The only problem is that I cant access my network from the public pc's
despite setting up routes and checking everything I cant figure it out. I
can however use a pc behind the nats on the BIG to access a pc on the public
side. I am absolutely baffled with this. I wouldn't mind if it was the other
way round, but now I have to send an email to myself and retive it on the
other pc's to print a document on the same network lol.

If anybody has had any experience with the BIG and SAR 715, and would like
to help let mw now.

Thanks for the help guys.
