1. Yes, with iptables you can redirect requests to another port number (where other Tomcat instance runs, or just some other web server). There is an example of redirecting from port 80 to port 8080 using iptables. https://wiki.apache.org/tomcat/HowTo#How_to_run_Tomcat_without_root_privileges.3F Note that there exists the "proxyPort" attribute on <Connector> element that will tell Tomcat what its public port number is. 2. Maybe you can redirect selectively by remote host address (I do not remember iptables docs so throughly, but I think it is possible), but an easier solution might be to just add a different Connector with different port number (and maybe with address="127.0.0.1" if you are connecting locally) that you would use for administering.
