> Paul, you are using /32 as the netmask, was it intentional?

Now that was a good hint :-)
If I use /24 as 'Subnet Mask' in Yast 'Statically Assigned IP Address' then 
'route' command now gives the expected paths

linux-64l2:/etc/sysconfig/network # route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         192.168.131.100 0.0.0.0         UG    0      0        0 eth0
192.168.131.0   *               255.255.255.0   U     0      0        0 eth0

I think Yast should complain about /32 as Subnet Mask instead of creating a
system without gateway (and leaving the user clueless) ?

Anyway, thank you for your support.

Paul.
