<html><body>Hi all, Been reading a lot about Port 80 for IPA and firewalls but have not found a concrete answer. I know the redhat docs indicate port 80 is required bidirectional however I need to investigate if it is truly needed. GUI only responds to 443 so not sure what else would be utilizing port 80. I have seen some references that dogtag proxies its ports to 80 and 443 but if the gui is running on 443 does that mean dogtag is proxying via 443 only? Or is there a way to tell? Has anyone attempted not opening port 80 from IPA Server to IPA Server and clients to IPA server? ipa-server-3.0.0-50.el6.1.x86_64 Sean Hogan </body></html>
