Hi all,
I have installed a lab environment with two different firewalls on it
to communicate with another production environment. In this test
enviroment, I have setup five servers: three with rhel5 and two with rhel4.
As I said earlier, in this environment exists two firewalls to provide
communication to another LAN's: fw1 and fw2. Where is the problem?. The
problem is as follows: sometimes fw1 is up (but sometimes not) and
sometimes fw2 is up (and sometimes not). I need to monitor network
interfaces but how can I configure policy routing on this five servers
to detect which firewall is up and insert the correct default route?? I
need similar funcionality that ifstated provides on OpenBSD
(http://www.openbsd.org/cgi-bin/man.cgi?query=ifstated&apropos=0&sektion=0&manpath=OpenBSD+Current&arch=i386&format=html).
Are fw1 and fw2 ever up at the same time?
Why not use RIP and let the FW's advertise routes via RIP? I've not done
that in a while....but it used to be gated but now I hear quagga is what
you'd use.
