RHEL: How does iptables work with ip_conntrack for UDP connections?
Issue
UDP
connections are stateless. How can I trackUDP
packets in the kernel and use the state information for matching onip_tables
rules?- Why is my
UDP
application output datagrams is occasionally missing aniptables
rule with-m state --state ESTABLISHED
?
