Hi folks,
Forgive me if this doesn''t come out right, but I have the flu and
I''m miserable
and not thinking clearn.
We just got satellite internet (''YAY for me! Been on dialup since
1995!). Three of
us are plugged into a router but there is no, ummmm....we can''t see
each others''
systems.
Thing is, when I go to grc.com to check the firewall, it used to be stealth,
but
now I keep getting something about ''Your system REPLIED to our Ping
(ICMP Echo)
requests''.
Is there something special I''m supposed to do now that I''m
behind a router?
John

It''s three stand-alone systems (me, my 73 year old mom and her 77 year old boyfriend). Nothing special. We''re all three going to a wireless router that goes to the satellite modem. My mom and I use linux, her boyfriend uses wondows. I have shorewall on me and my moms\''s syetem. When we were each seperately plugged to the internet via dialup, we were both stealth, but now that we''re going to a router which goes to a satellite modem, I can''t get stealth.

If I understand correctly all PCs are connected wirelessly. There is an option in the router''s configuration under "Wireless Advanced": Enabled AP Isolation - This function can isolate wireless stations on your network from each other. Wireless devices will be able to communicate with the Router but not with each other. To use this function, check this box. AP Isolation is disabled by default. If you have enabled this the PCs won''t be able to see each other regardless of how your firewalls are configured.
