Three Computers - Hub - Print Server

Computer A - WinXP - Thru Hub - Ethernet Card - Fixed IP Assigned
(192.168.0.1) - DNS Gateway Assigned (192.168.0.2)

Computer B - WinXP - Ethernet Card #1 - To Cable Modem (Internet
Access) - Floating IP - Floating DNS
Ethernet Card #2 - Thru Hub - Fixed
IP Assigned (192.168.0.2) - Floating DNS

Computer C - Win98 - Ethernet Card - Fixed IP Assigned (192.168.0.3) -
DNS Gateway Assigned (192.168.0.2)

Print Server - Fixed IP Assigned (192.168.0.5)

Would like to connect A and C to and thru B for 1) File sharing and 2)
Internet access (B is Firewalled with Norton - thus hopefully I can
access the Internet from both A and C using the protection installed
on B).

Norton Firewall on B set to accept 192.168.0.x as "trusted". MS
"Internet Options" firewall on A set to accept 192.168.0.2 as
"trusted". MS "Internet Options" firewall on B set to accept
192.168.0.1 and 192.168.0.3 as "trusted".

A and B can see each other and C for file sharing - but A can not
access the internet via B. The view out from C (Win98) is still an
island to everything. No files or internet. NetBIOS selection is
ghosted out on the tab on the C computer.

Using the Network Wizard sometimes builds a Bridge - yet Internet
access does not work in any case. What is "bridged" - IP Addresses on
a single computer? Do I need to build bridges?

Under Advanced TCP/IP Settings what should be added or checked - DNS
Tab? WINS Tab? Options Tab is TCP/IP filtering - Properities = All.

The two computers running WinXP also have 1394 LAN Connections
Enabled. I have been ignoring these - is this correct or should I
Disable?

C seems to be a Win98 problem. No clue on the internet access issue
from A.

Priority is 1) to get (protected) to the internet from A, 2) internet
access and file access to A & B from C, 3) Print server - I have not
even tried this yet.....

Confused......advice sought.

TIA

Easiest solution would be to switch to an ethernet broadband router.
Software firewalls would be redundant in that case.

In your situation you should not be running both the Norton firewall and the
XP firewall on B. The XP firewalls on A, B should accept 192.168.0.xxx as a
trusted network. All computers must be in the same workgroup, address range
and subnet mask. The only DNS server you have at present is your IP, which
is only valid for B, so no DNS on A or C or the LAN adapter in B.

You don't need/want a bridged connection.

You do need either NAT or a proxy server to access the internet from A or C.
NAT is preferable. In the absense of a router to provide NAT you can use
XP's Internet Connection Sharing, which provides NAT and DHCP services.

In that case you must to set the LAN ethernet card in computer B to IP-
192.168.0.1 and enable ICS. Create the configuration diskette when prompted
by ICS and use that to configure the other two computers. ICS will set up
DHCP addressing by default (the connection sharing computer will assign
valid addresses to the clients) but you can switch to manual if you wish.
Use 192.168.0.1 as the default gateway. If you want to use the Norton
firewall on B, it must be configurable to run on an Internet Gateway
computer, or else it is likely to block internet connection sharing. Don't
enable the XP firewall if you are using the Norton firewall.

You can ignore the 1394 LAN connections, or disable(not uninstall) them if
you are not intending to use them for anything.
