I'm setting up a new box and started out with ip forwarding enabled. This seemed to prevent internet access, so I tried disabling forwarding with yast, but this only caused a hang. I ended up having to walk to the datacentre to access the physical console.
Just wondering before I start digging into this - are there any (more or less) known issues wrt ip forwarding and/or the enabling/disabling thereof in 12.1 ?
