Routing Problem

[Chris Sibel]

Hey Everyone,
I'm trying to setup NAT IP routing protocol for my companys network.
I have a Windows 2000 Server with SP4 with 2 Network Adapters. I labeled
them 'Internal' and 'External'.

The 'Internal' adapter TCP/IP settings...
IP address "192.168.1.7"
Subnet Mask "255.255.255.0"
Gateway is "Blank"
DNS "66.63.128.33"

The 'External' adapter TCP/IP Settings...
IP Address "10.2.0.2"
Subnet Mask "255.0.0.0"
Gateway "192.168.1.1" (points to a Cisco Router)
DNS "66.63.128.33"

Keep in mind that we are using a Cisco Router to route Public IP's ranges
between '66.63.142.101' and '66.63.142.110' which goes to One-To-One of
'10.2.0.1' to '10.2.0.10'

So My goal is to allow a outside connection to enter, lets say
'http://66.63.142.101' and have that be routed to '10.2.0.1' (one-to-one).
Which will then be routed to a workstation on my LAN which I have a website
being hosted on (ie. 192.168.1.24).

When I goto a PC that is not on the LAN and enter 'http://66.63.142.101' in
the IE address bar; I'm able to see the inbound connection in the NAT
Mapping Table on the 2K Server but for some reason I'm not being routed to
the other IP. Do I have everything configured right?

IP Address "10.2.0.2"
Subnet Mask "255.0.0.0"
Gateway "192.168.1.1" (points to a Cisco Router)
DNS "66.63.128.33"

Hmm, how should the machine where 192.168.1.1 is ? Normally, the machine
and the gateway have to be in the same (sub)network

A question first, if you type 'http://66.63.142.102' into
a browser does it work?

I ask because the only static mapping you appear to be
using on the LAN side of the router is 10.2.0.2 , you
dont mention what 10.2.0.1 and 10.2.0.3-10 are assigned
to. I also don't understand your thinking with
the 'internal' and 'external' adapters why do you think
you need them?

I am running NAT throught a Cisco 3660 here and am using
both static and dynamic mappings to various machines on
the network, would like to help you so please contact me
directly by e-mail.

Regards

Michael.
