5.3. IPv6

Procedure 5.1. Disable the IPv4 Stack Java Property

1. Open the relevant file for the installation:

   • For a Standalone Server:

     Open EAP_HOME/bin/standalone.conf.

   • For a Managed Domain:

     Open EAP_HOME/bin/domain.conf.
2. Change the IPv4 Stack Java property to false:

   -Djava.net.preferIPv4Stack=false

   For example:

   Example 5.8. JVM options

   # Specify options to pass to the Java VM.
   #
   if [ "x$JAVA_OPTS" = "x" ]; then
      JAVA_OPTS="-Xms64m -Xmx512m -XX:MaxPermSize=256m -Djava.net.preferIPv4Stack=false 
      -Dorg.jboss.resolver.warning=true -Dsun.rmi.dgc.client.gcInterval=3600000 
      -Dsun.rmi.dgc.server.gcInterval=3600000 -Djava.net.preferIPv6Addresses=true"
   fi
   

Procedure 5.2. Configure the Interface for IPv6 Networking

1. Select the Configuration tab at the top of the screen.
2. Expand the General Configuration menu and select Interfaces.
3. Select the interface from the Available Interfaces list.
4. Click Edit in the detail list.
5. Set the inet address to:

   ${jboss.bind.address.management:[ADDRESS]}

6. Click Save to finish.
7. Restart the server to implement the changes.

Procedure 5.3. Configure the JBoss EAP 6 Installation to Prefer IPv6 Addresses

1. Open the relevant file for the installation:

   • For a Standalone Server:

     Open EAP_HOME/bin/standalone.conf.

   • For a Managed Domain:

     Open EAP_HOME/bin/domain.conf.
2. Append the following Java property to the Java VM options:

   -Djava.net.preferIPv6Addresses=true

   For example:

   Example 5.9. JVM options

   # Specify options to pass to the Java VM.
   #
   if [ "x$JAVA_OPTS" = "x" ]; then
      JAVA_OPTS="-Xms64m -Xmx512m -XX:MaxPermSize=256m -Djava.net.preferIPv4Stack=false 
      -Dorg.jboss.resolver.warning=true -Dsun.rmi.dgc.client.gcInterval=3600000 
      -Dsun.rmi.dgc.server.gcInterval=3600000 -Djava.net.preferIPv6Addresses=true"
