I setup two identical Servers (with OpenSuse 10.2) as firewalls and
installed the second one by an image. Unfortunately all interfaces of
the first server are present at the second server plus additional
network interfaces (because of the different hwaddr) of the network
cards in the second server.
On the first server I have
- one onboard eth that is mapped to eth0
- and a four port D-Link DFE-580TX card mapped from eth1 to eth4
On the second server I have the same plus:
- one onboard eth that is mapped to eth6
- and a four port D-Link DFE-580TX card mapped from eth5 to
These servers should run as cold/warm/hot standby firewalls (with
fwbuilder) and I now have the following questions:
- how could I change the network interfaces from the second
server to also eth0 to eth4?
I read that this could be achieved by persistent
interface definitions but I don't know if that is
supported by fwbuilder
- how could I achieve to have both firewalls up and running?
I would change the external ip address of the second
one and in case of failure,
I change that address to the ip address of the primary
fw. If I do that I will have the problem, that either
the interface address in the policy is not correct or
the ip address in linux itself is not correct and I will
loose the connection and won't be able to access the
firewall from remote.
- the 4th port of the D-Link card is not working properly and is
also discovered as Sundance (not as DFE-580TX) like
the other 3 ports of the same card. How could this be
Any hints are much appreciated.
Thank you for your help.

If it's anything like Mandriva 2007, it's using UDEV and udev is what is
keeping track of your interfaces. Go into your /etc/udev/rules.d
directory and look for the network-config rule. You'll see your eth0-4
with the old MACs and your new interfaces. Delete the old lines and
rename the new ones to your liking. Restart your machine and you should
