What is the proper iptables configuration for Apache Solr on CentOS?

view story

http://serverfault.com – I know for a fact that iptables running is causing my instance of Apache Solr to be inaccessible. How do I know this? Because I ran: /sbin/service iptables save && /sbin/service iptables stop Once I did this, everything worked flawlessly. I would like to continue using my firewall however, adding the necessary rules for it doesn't seem to be working. I have exhausted what I thought would work: /sbin/service iptables start /sbin/iptables -A RH-Firewall-1-INPUT -p tcp -s --dport 8983 -j ACCEPT /sbin/service iptables save Still not working /sbin/iptables -D RH-Firewall-1 (HowTos)
