Firewall on only one of 2 nics ?

[- Bobb -]

2 pc network - with 2 nics each . One for public internet and one for
intranet sharing (10.10.10.x).
Anyway to use firewall for the public nic and turn off for intranet ?
As it is, when I need to use intranet, to be safe, I have to disable the
internet nics, turn off the firewall - use the private network - move the
files - re-enable firewall - reenable public network nics - continue -
rather tedious.
On one Pc , I have XPand using XP firewall. Other is Win2000 and Zonealarm.
In XP I enabled firewall for just the one nic but it acts as either its on
for all or off for all.

Get one of these for $40 or so.

Dave,

I DO have a Linksys router and use it for my internet connection. I have 4
PC's online and want to connect just these 2 via crossover . History: I'm
migrating from one to the other and have a LOT of stuff on the original. I'm
trying to keep the new one free from " old / no longer needed files" and do
find that I may need an old program / folder. I could copy all 3gb of my
"old stuff" (going back to Win95 days) from old to new - would prefer to
only put on there what I find that I need - otherwise I end up as a packrat.
That's why I'd like the 10.x.x.x connection open too while online - but not
urgent.

You are making far too much work for yourself. It is normal to configure
a firewall to allow lan traffic and to firewall Internet traffic. You
do not need to use separate nic's to do this. You do not need to make a
new crossover peer-to-peer connection - you already have a lan with
private IP addresses using the Linksys default of 192.168.1.xxx. You
can transfer files perfectly over your 192.168.1.xxx lan. Configure
your firewalls on each computer to allow the IP range
192.168.1.0-192.168.1.254 as trusted.

I agree - that would be easier , but I don't like checking that "file
sharing" box on my primary (internet) NIC.
If the router should get flaky and someone in the family were to move the Pc
cable right into cable modem ...
This way I know that only way to get the files is via 2nd nic.
AND , I just found that if I wait long enough (times varies) , then my setup
DOES work.
For some reason it takes "a while" before I can see the W2k box from XP.
After " this period" I can browse to " My network places " and see the w2k
share / folders fine.

I'll play a bit to see how long / why , but nothing in event logs.

Then get yourself a cheap hub or switch and connect your two computers
together using 10.x.x.x and transfer your files. You won't have an
Internet connection on those two computers.

If you want to make more work for yourself, who am I to say no? But I'd
just buy an extra router and shove it in the closet for a replacement
instead if you're worried. Then you could explain to your family to
always use a router and show them where the replacement is kept. Plus
you certainly should have software firewalls on your machines, and they
will be doing their job of protecting you on the WAN side.

The computer browsing is an entirely different issue. Network Places is
not always reliable. It is easier to forget about it and just make
shortcuts to network shares instead.
