Leo,

Hi, I am looking to set up a firewall in my home that will allow me to set up a seperate profile for each person in the household. I have five children ranging from 18 to 4 and would like to set up distinct whitelists for each person. I have been able to find a firewall that supports setting up a profile by category to block but have been unable to find one that gives me the flexability to block by category for some uses and by whitelist for others. Please keep in mind that multiple people use the same computer.

Thanks for your help

I have a wireless windows xp computer and just recently my computer will not hook up with the interent. I have tried everything. Could the firewall be preventing it from accessing it?

Copy - paste doesn't work properly when I'm online. Offline it works no problem.

When I try to paste a web page into a Word or Excel document it doesn't format properly while I am online. I have Word.exe and excel.exe blocked in my mcaffee firewall. However when I unblock them they copy paste fine but it takes a while because it does some accessing or something but it shouldn't need to because the data is already there. What is happening?

Why does copy-paste work when I'm offline but not when I'm online?

Can I make it work so that the copy-paste feature works while I'm online with Word and Excel blocked in my firewall? Dial up internet is very slow, so speed is a factor, I don't want to have to wait and shouldn't have to every time I want to paste something into word or excel.

Why does it do this?

You note that the downside of a hardware firewall is that it only blocks incoming, not outgoing traffic. Then for a software firewall, you recommend the built-in Windows XP firewall. However, unless things have changed since I last looked into it, doesn't the XP firewall block only incoming as well and let all outgoing go, no matter what?

What happens when you try to turn on the firewall?

The firewall will not stop all types of popups. You need to make sure that popup blocking is enabled in yoru browser, and make sure to run up to date anti-virus and anti-spyware tools regularly.

Hi... pls help me or give me some suggestion :)

I have 2 firewalls in my office, Firewall A and Firewall B

Firewall A (the one connect to Internet):
trust ip: 192.168.1.1/24 (static IP)
untrust ip: DHCP (ISP assigned)
NAT is on at both trust and untrust interfaces.
DNS set.

Firewall B (connect to my NIC):
trust ip: 192.168.11.1/24 (static IP)
untrust ip: 192.168.1.34/24 (static IP)
my pc ip: 192.168.11.2 (static IP)

The picture is:
Internet --- Router --- Firewall A --- Server --- Firewall B --- my pc

When I try to login into my PC, it said, Domain server was unable to validate my password. I have been told if i set the IP as static in my PC, just ignore that error message.

Do you have any idea what went wrong?
Thank you very much....
