Firewall and nmap

I get odd behavior when I test my firewall through
Three random responses come up: says it can’t ping my computer, or that ports 53 and 80 are open, or
all my ports are filtered…anyone else have this problem? Is it the firewall or nmap?

Hmm…I don’t get this problem. What mode is your firewall on?

I am in Custom Policy mode and I set the stealth ports wizard to “block all incoming connections.”

Do you have a router (not a modem that you get from a cable or DSL company)?

I have a direct connection, no router of any sort.

Sorry, can’t help you. Maybe a staff member will reply. But it may help some people if you said what OS you have.
