Linksys WRT54G: Laptop send unsolicited packets

Have a question or want to start a discussion? Post it! No Registration Necessary.  Now with pictures!

Threaded View
To enable file sharing between my desktop and laptop I had to diable
the firewalls on both computers (XP firewall on desktop and Trend
Micro firewall on laptop).  

I used the www.grc.com web site to test the protection provided by my
Linksys broadband router.  My desktop passed everything with flying
colors, but my laptop failed by sending unsolicited packets.

If anyone has any ideas why this would be happening and what I can do
about it I'd really appreciate a reply.

I'd really like to have firewalls on both computers and in addition to
the router firewall.

Thanks in advance,
James

What do you mean that a machine behind the router sent unsolicted packets?
What test are you talking about?

I just set up a network for my desktop and my laptop (Netgear fast
ethernet card in the Desktop and a Netgear WG311 wireless card in the
laptop and linksys WRT54G broadband router).  At first, I couldn't get
the computers to see each other until I enabled "netbios over TCP/IP"
and turned off the firewalls on both computers.

I went to the www.grc.com web site and used the "ShieldsUp" tests to
make sure the linksys firewall was adequately protecting my computers.
When I ran the tests from my desktop, I passed all the tests.  When I
ran the same tests from the browser on my laptop (sharing the internet
connection of course through the router) it was reported that my
security system had tried to counter-probe the test site and thus was
exposing itself (unsolicited packets received).

Since I posted my original message, however, I've run the test again
and passed.  I.e, it's no longer trying to counter-probe.  I'm
mystified.

I've learned also that I can set up my firewalls to allow certain
exclusions so that my networked computers and router can do what they
need to, but I'm in the early stages of leaning how to do this.

For now, I have to trust that my router is protecting my computers.

After all my rambling, do you perceive enough to give me any advice.
I've already learned alot from reading your other replys to posts in
this group.

Thanks

I suspect he is talking about leaktest at grc.  Leaktest is an
'extrusion' detector.  It tries to simulate malware running on the
user's computer.  You download and run the app and it leaks thru'
intrusion detectors.  http://www.grc.com/lt/leaktest.htm

I guess.

I ran the "TruStealth" online tests for common ports and all service
ports.

It seems to be some kind of browser test. You should configure the browser
to pass the test.

Go to this URL:

   http://www.grc.com/default.htm

Go down the page a little more than half way, and find the
button for ShieldsUp.  Click on it.  Compare the URL listed
on your web browser with the one above that you think is
a "browser test".

Now try access it with the browser's "reload" button, or try
to access it directly by URL as you did last time.  This time
read it carefully and see if it makes sense.
