Suse Firewall: can see in but can't see out on mixed Windows/Linux LAN

I have a small LAN with mixed Windows XP and Suse Linux 10.2 installations.  It I turn off the Suse firewall I can see my Windows PC's when I browse the network from the Suse side.  If I turn on the firewall, browsing the LAN fails.  I can see the Linux box from all the  Windows PC's with the Suse firewall enabled.

Here are the current settings:

Internal Zone
No interfaces assigned to this zone.
Demilitarized Zone
No interfaces assigned to this zone.
External Zone
Interfaces
Realtek RT8139 / eth-id-00:e0:7d:ac:d5:14
'any' Any unassigned interface will be assigned to this zone.
Open Services, Ports, and Protocols
DHCP Client
HTTP Server
Samba Server
TCP Ports: 10000, 21, 8080, epmap

Another weird thing:

If I stop the firewall, I can browse the other PC's on the LAN, and if I re-start the firewall I can still browse the LAN.  However, next time I reboot the firewall (with exactly the same settings) blocks LAN browsing unless I manually stop and restart it.  I can't understand this.

Try to assign eth0 to the Internal Zone on all SuSEs.
