Hi
Looks like you are loving suse 10.1 just like i do
I am Fedora user, and those little things are a little surprise for me
I had to install suse router for one company, and another at my home as training platform, etc.
The funny thing is that if you change something, please check network cards config in yast, and routing and firewall things too. Sometimes you have to reconfigure all the stuff several times in a row, BEFORE it starts working. Of course, only reboot helps. But with no guarranties which reboot
The problem most probably is in that you are changing network cards (MAC differs), and IP addresses. Config tools are very lame in handling this flawlessly.
So you have to CONFIGURE & REBOOT, CONFIGURE & REBOOT, until it works.
during that process you can and can not ping one ot another computer, etc.
That's from dumb user perspective
In my opinion, the only thing that works without problems is when you do all the things manually, like in old good times
In my case I found that these CONFIGURE & REBOOT is the only thing that helps. I'm not interested in digging through all the internakl things like i learned on Fedora.
Also, Suse is quite "specific", if compared to Fedora. I hope they will improve its quality level in all dimensions.
