Have Linksys wireless home network with Speedstream dsl modem to get
us on-line. Three machine on network ..two Macs with 10.4.6 OS and
one Win2K. Each machine has its own firewall. MACS have preinstalled
ones that came on machines and Win2k has Sygate firewall. DSL modem
has its own firewall as does Linksys router. Are all three firewalls needed? I have suspicion that poor performance in some of video
conference applications might be attributed to everything having to
be filtered by three different firewalls. Firewalls on individual
machines easy to disable but the ones on modem and router are not so friendly.
On your Windows box you can't have too many firewalls because there is
just so much malware out there. Even then it isn't safe from malware
you install yourself or can be tricked into installing.

There is no need to have any more than one firewall. Sure you can have 2,3,4,5,100 but if the first one is operating properly and blocking
incoming requests and unauthorised ougoing requests then there is no
need.
Plus imagine having to configure port forwarding through 3
firewalls, it would be a nightmare for most people.
Software based protection is mostly useful for people that don't have a firewall/router. If you have a firewall router that is configured
properly there is no need to activate any other firewall between your firewall/modem/router and any machine/router attatched to it.

What if the firewall is compromised? What if it's misconfigured?

You don't need to configure port forwarding more than once if you filter--- Synchronet 3.18b-Win32 NewsLink 1.113
at the DSL router and at the hosts (port forwarding doesn't need to be
done on the hosts).

For a small network where the admin knows what he is doing software protection on the hosts is probably not needed but many larger corporate networks, ones with many points of ingress including breaking and
entering into a small branch office, are filtering at the host now.

I am still struggling with this prob. I even tried disabling all three
just to see what would happen on trying to initiate video chat
application (iSpQ) and got the message that I was behind a NAT firewall
and to disable it. What is an NAT firewall?
