There are a couple of things you can do. You can add the new IP in InterWorx ( but it will not be available unless InterWorx is running) or you can edit the appropriate ifcfg script (found in /etc/sysconfig/network-scripts) and InterWorx will detect the new IP address. If done this way, you’ll have to restart networking and you will have to run “/home/interworx/cron/ip.pex --sync” the IP address will be available all the time.
