I have just setup and started running my new Christmas Wireless Internet connection hardware. Connections are working great. My question is about my Zone Alarm firewall blocking outgoing from "Source IP" 192.168.1.x:xxxx to "Destination IP" 192.168.1.x.xxx . I think this just started up after setting up my wireless stuff. I don't remember seeing it before. What does this mean? Should I worry about it? Thanks, John


More clarification:

Discription from ZA: "Packet sent from 192.168.1.x (NetBIOS Datagram) to 192.168.1.x (NetBIOS Datagram) was blocked"

I get this if both directions, incoming and outgoing.

The port numbers vary, but always in the 1xxx range. Sometimes there is no port # listed. Sometimes it says "NetBIOS Session" other times it says "NetBIOS Datagram".

Would that be the trusted zone under the ACCESS or SERVER heading?

Hey Daniel, I am slow but steady. With your insight and some more looking at ZA help files I figured out how to add that IP # to the trusted zone. Thanks a Million, John

It sounds like your local subnet is not on the trusted list. you should add the subnet to the trusted zone. I've noticed the pro version detects and does it automatically. But maybe the other version(can't remember) doesn't.

What port numbers were being accessed? Netbios I think is 445??? or something like that.

If the 192.168.1.* was in the trusted zone you wouldn't get it at all. Its seeing packets outside of your pc as 'on the internet' even though they are local.

Like I said if anything in the 192.168.1.* range is getting blocked its because its not trusted and therefore not considered 'local' traffic.

I have zone alarm pro at the moment, and under firewall, theres an option for zones where you just add 192.168.1.0/255.255.255.0. As that trial expires tonight I'll downgrade it and check for you...

ok take a look at

formatting link
which is the manual...

Under firewall protection then managing traffic sources is the information you need. Basically you select firewall, then within that the zones tab. the make sure your network is listed as a trusted zone. (assuming all pc's on this network are your own of course!)

Kind regards,

Daniel
