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?
No. Only one firewall is up.
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.
Well, I will try it ...
