Subject [users@httpd] Firewall settings for mod_jk
Date Fri, 11 Feb 2005 03:20:03 GMT

With Apache2 is going to send requests to Tomcat's port 8009 via Ajp13.

Is there any way to know ahead to which port Tomcat is going to respond, 
or is mod_jk
connecting from truly random high ports?

I would like to be as restrictive as possible on the firewall.

Thank you,
