Hello Senol, Hello all, I my special case I want to setup a 2 Node Active/Passiv failover Cluster with nagios ( nrpe/snmp ) as a service. ClusterNode1IP - -> vIP ----------- Clients (connects only allowed from vIP) ClusterNode2IP - The nrpe and snmp Agents only allow connects from the virtual IP of the Cluster. An iptables nat rule should do that for these ports. But is there a best practice ? Thank you Hi Bernd, your comments too much close but; - if u are build two node fail-over (as Acrive-Passive) you can give to vIP to active node starting, - if u are using two or more server at the moment (for Load Balancing) then your keywords "ipvsadm" and "Direct Routing". 2010/8/18 Bernd Broermann <bernd broermann com> Hello, How can I define a resource to make all outgoing network packets appear to be the virtual IPaddress ? I mean something like the "ipsrcaddr" resource in OCF:heartbeat.
