I use ZoneAlarm Pro but I’m not sure I’ve got my ‘zones’ set up correctly.
I’ve had some problems getting the computers to print over the network. I
can with one wireless connected computer but not another. All PCs run WinXP
HE SP2.

Hardware setup:

I have 3 computers (each running ZAP) attached to a KCORP KLG-575 wireless
router ( 2 wirelessly and 1 via ethernet cable). The router has an inbuilt
hardware firewall which I use on default settings ( the router’s firewall not
its security settings). The router is connected to the internet via a DSL
modem (D-Link DSL-300T).

My zone settings are:

Network (ADSL modem): internet zone 192.168.1.0
Wireless router: internet zone 192.168.1.1
Computers 1 - 3: trusted zone 192.168.1.100 / 101 / 102

Is this correct, or should I put the router on ‘trusted’ also?

I know I strictly don’t need a software firewall for incoming packets but I
want to lock down as much as I possibly can.

Thanks in advance.

Steve
