Could anyone help me with this please?

Daddy:
WinXP Pro
ZoneAlarm Pro
Wireless connection to Internet
Network Card to connect to "Mummy" (the wife's) PC

Mummy:
WinMe
ZoneAlarm Free
Network Card to connect to "Daddy"

"Mummy" accesses the Internet thru "Daddy" just fine until Zonealarm
Pro is started in "Daddy" - then "Mummy" just keeps waiting for
response or gives "page not found"

ZoneAlarm Pro in "Daddy" shows 2 "zones":

1. name=Wireless, IP=10.10.0.0/255.255.255.0,
Entry Type=network, Zone=Internet

2. name=LAN, IP=192.168.0.0/255.255.255.0,
Entry Type=network, Zone=Trusted

In Daddy's ZoneAlarm Pro:
Internet Zone Security is set HIGH
Trusted Zone Security is set LOW

In Daddy the local connection is defined as:
TCP/IP Protocol :
IP/SM = 192.168.0.1/255.255.255.0

In Mummy the LAN connection is defined as:
TCP/IP Protocol --> Ethernet Adapter :
IP/SM = 192.168.0.2/255.255.255.0

So why does ZoneAlarm say 192.168.0.0 (that's "zero, zero" on the
end)?

As I said, it all works fine WITHOUT ZoneAlarm Pro activated in Daddy.

When ZoneAlarm is activated in Daddy then Mummy can't even surf.

Attempts in Mummy to surf to the "Google" site give an "Alert" in
ZoneAlarm in Daddy with the following characteristics:

Type = Firewall Alert
Protocol = TCP/IP (flags:S)
Source IP = 10.10.0.35:61423
(10.10.0.35 is the IP address used by Daddy for the WAN connection -
although Zonealarm states it in the "Zone" section as 10.10.0.0)
Destination IP = 64.233.161.147:80 (=Google)
Direction = Outgoing
Action Taken = Blocked

The Windows XP Firewall is disactivated in Daddy.

Does anyone have any ideas?
Keep it simple - I'm not very clever :(
And, english is not my native language :-(
Also, if this is the wrong group to ask this then I would appreciate
being pointed at the right one.

TIA for any help. I'm at a loss here :-(

... and "Mummy" (the wife) gets upset if "Daddy" (I) puts the
ZoneAlarm Firewall up :-(
