Hi all,
I have set up an IPVS loadbalancing for Web traffic that is working perfectly.
But now, I try to run my usual firewall script (IPTABLES commands) on the director server and packets seem to be blocked while being sent to Apache server.
I can notice with ipvsadm counters that my http queries are taken into acccount and that director try to send packets to final server ..but nothing arrives on the Apache server.
Maybe IPTABLES and IPVS are not compliant ?
Many thanks for your ideas,
I've solved this problem by adding iptables rule that ACCEPT packets with state NEW and INVALID from source RealServer
Sorry, but I don't know exactly which chain could be added this rule in, because I use one chain for INPUT and FORWARD:
iptables -t filter -A INPUT-FORWARD -m state --state NEW,INVALID -m tcp -p tcp -s source --sport source_port -j ACCEPT
source and source_port are Real Servers and Ports that used in IPVS (LVS). For simplicity, I use source_net instead few sources
Hope it will help somebody!
By the way I use LVS-NAT
