Routing http & email in a home network

[Ian Blackwell]

Hi,

I have a Windows 2000 Pro PC running Internet Connection Sharing. The W2k PC
is
connected to the internet semi-permanently through an ISDN connection that
drops out and reconnects every 5 hours or so (ISP initiated). I use
www.zoneedit.com for dynamic IP DNS of my domain name due to the varying IP
address I am assigned each time the ISDN reconnects.

I have a small home network behind the W2k PC including a Fedora 3 server
that I want to use for httpd and sendmail. The W2k PC is the device that
has a public IP address - all other machines, including the Fedora server
use statically assigned 192.168.0.x addresses.

My question is this: What do I need to configure on the W2k PC to redirect
httpd and sendmail traffic to the Fedora server? I've added the Fedora
server's IP address to the host table on the W2k machine with for the public
domain name, but that didn't seem to help much.

Thanks in advance, and if you think there is a better group to post this
message to, please let me know also.

Since you are using IPC for address translation and routing
you can map incoming connections on that machine to the
internal service machines (by IP and port number.)

It's a dialog on the NIC of the EXTERNAL (shared)
connection -- located with the Firewall settings.

My question is this: What do I need to configure on the W2k PC to redirect
httpd and sendmail traffic to the Fedora server? I've added the Fedora
server's IP address to the host table on the W2k machine with for the public
domain name, but that didn't seem to help much.

Microsoft (in XP) added the firewall and uses the
same dialog pages to merely open incoming server
connects as they use for opening and mapping them
to other machines to provide those services.

In the latter case, you not only open the external port
but send it to an internal IP and port combination.

Hi Herb,

Not sure I follow you entirely. I'm running W2k Pro, not XP, so I am using
McAfee Personal Firewall Plus v6 in the absence a firewall supplied with the
OpSys. The shared internet connection is simply a DUN connection using a
128k ISDN modem instead of a 56k modem, and I can't see any dialogues there
that will help me.

Cheers,

Ian

Hold the phone!

I found it under the Sharing/Settings/Services dialogue of the DUN
connection.

Thanks for pointing me in the right direction - greatly appreciated!

Sorry about the 2000-xp confusion but the key point was
the ICS which is nearly the same -- the main difference
however is that in 2000 the service-port mapping is NOT
in the dialog for the firewall since 2000 doesn't have the
firewall, but is just there alone

The shared internet connection is simply a DUN connection using a
128k ISDN modem instead of a 56k modem, and I can't see any dialogues there
that will help me.

Doesn't matter it still has the same mappings.

And your other message indicates you found it
on your own once you had the hint.
