So you want Tomcat to listen on all IPv6 addresses plus the IPv4 loopback address but no other IPv4 addresses? Since you've told the OS to not allow IPv4 connections on IPv6 sockets, I believe you would need to configure a separate <Connector> on the same port for the IPv4 loopback address. > > So, reading here - > http://tomcat.10.n6.nabble.com/Tomcat-uses-IPv6-td2164369.html#a2164371 > - and elsewhere, I set > > vi /etc/tomcat/tomcat.conf > ... > JAVA_OPTS="Djava.net.preferIPv4Stack=true > -Djava.net.preferIPv4Addresses=true" > CATALINA_OPTS="Djava.net.preferIPv4Stack=true > -Djava.net.preferIPv4Addresses=true" > ... > > now, @ tomcat start, > > ps ax | grep tomcat > 6530 ?
