We've got an existing server cluster using it and are only trying to add new machines; changing the setup for the machines already in the LVS is not really an option. We found this: http://www.ultramonkey.org/3/topologies/sl-ha-lb-eg.html And adapted it as follows: # yum install arptables_jf (if necessary) # /etc/rc.d/init.d/arptables_jf stop Flushing all chains: [ OK ] Removing user defined chains: [ OK ] Resetting built-in chains to the default ACCEPT policy: [ OK ] # /sbin/arptables -A IN -d [virtual_ip] -j DROP # /sbin/arptables -A OUT -j mangle -o eth0 -s [virtual_ip] --mangle-ip-s [realserver_ip] # /etc/rc.d/init.d/arptables_jf save Saving current rules to /etc/sysconfig/arptables: [ OK ] # /sbin/chkconfig --level 2345 arptables_jf on # /etc/rc.d/init.d/arptables_jf start Flushing all current rules and user defined chains: [ OK ] Clearing all current rules and user defined chains: [ OK ] Applying arptables firewall rules: [ OK ] Then do "arptables -L -v -n" to verify that the rules were installed correctly.
