Using WinXP firewall with LAN ?

[Malcolm H]

I have a broadband connection via cable modem and ethernet broadband router
(D-Link DI-604)
to three PCs (one WinXP and two Win98). I can connect to the Internet from
any of the PCs via the router.
However I also wish to have full LAN connectivity between the three PCs.
This only works if the WinXP machine has its WinXP firewall disabled. If I
enable the firewall then only the two Win98 machines can communicate via the
LAN.

Is there any way I can leave the WinXP firewall enabled and still have full
LAN connectivity??

You MUST disable the WinXP firewall on a LAN connection. It was
designed for use only on a direct modem connection to the Internet.
It serves no useful purpose on a LAN, and it blocks file and printer
sharing. Details here:

Your broadband router acts as a firewall, protecting your computers
from access by other Internet users.

Just for my own information, will the router stop outbound traffic?

Hi, Ken. The broadband routers that I've seen only protect against
undesired incoming traffic. For protection against undesired outbound
traffic, install a firewall program with that capability. Be sure to
configure the firewall program to allow access by your LAN computers.

Many thanks for the reply.
I just started to follow this newsgroup as I wanted to learn about
networking.
A lot of fascinating information, but still very confusing at times.
I read many of your posts as I think you give the most knowledgeable
answers.
Thanks again
