Hello World :) I am interested in following scenario with iptables (if such is possible). Setup: 1. Ext Firewall nats port Z to server A. 2. Application X listens on port Z of server A 3. It happens that application X crashes for a couple of seconds and get's restarted by a monit. Question: Is it possible to perform Nat on server A itself, to server B, that will took place only until application is restarted (only while no one is listening on port Z) otherwise expose port Z to back to application. Reason: The idea is to provide a failover, uninterrupted service even when app crash occurs. P.S. Please without "why you are this and that..." questions instead suggestions. I need it the way i need it, questions are if it is possible, and, if yes, how :) P.P.S. It's tcp traffic, non persistant connections. Thanks for help in advance!
