Linux iptables can interfere with load balancing of traffic and must be disabled on the Dispatcher machine.
lsmod | grep ip_tablesThe output from the preceding command might be similar to this:
ip_tables 22400 3 iptable_mangle,iptable_nat,iptable_filterIssue the following command for each iptable listed in the output to display the rules for the tables:
iptables -t <short_name> -LFor example:
iptables -t mangle -L iptables -t nat -L iptables -t filter -LIf iptable_nat is loaded, it must be unloaded. Because iptable_nat has a dependency on iptable_conntrack, iptable_conntrack also must be removed. Issue the following command to unload these two iptables:
rmmod iptable_nat iptable_conntrack
