concepts. The firewalls I'm talking about are on each machine in the house connected to the NAT router, which in turn is connected to the Internet. So from your last remark, they are all protected by the router, and do not need to be running separate software firewalls themselves? T
depends...
are all the computer of your network safe?
for example, is there on your network a computer running Windows and can be compromised by a mail virus? Do you have a familial wifi network (that somebody on the vicinity can compromise)? Do you have some time friends that come with a laptop and have to be connected through your network? Did you buy recently a printer (most new printers connect to internet and may be compromised)?
We live in a rural area, so the wifi is unlikely to attract passers-by. It also has a fairly long, non-intuitive password. But, yes friends do visit and want to connect their devices to the Internet.
on the other side, a firewall on your desktop uses very few resources, so why not?
Which brings me back to the original question. Machine A is running a web2py server on a non-standard port on the private LAN. I want machine B to be able to access this web server from another room in the house. The firewall in Yast2 prevents this in its default configuration.

On the machine the web2py service runs on: In the file: /etc/sysconfig/SuSEfirewall Search for pattern: FW_SERVICES_[A-Z]*_TCP= Add (separated with a space, if necessary), your web2py port 8xxx. Restart the Firewall, test. non-standard port = manual config.
