>We do it all the time. Redhat has a few very good KB articles on how to set up iptables to support RHCS Hi, I believe I found the article you reference, http://kbase.redhat.com/faq/docs/DOC-8782 and enabling it on a passive node causes no issues until migrating the service. It just silently fails w/o any specific indication as to why in the logs? Do your rules mirror what's documented in the above article?
