Aside from how to invoke it, does the service config really needed changed? Could you possibly listen to 0.0.0.0 and just restart the service?

I don't deal with CentOS but I believe it has an ifup-local script. You could possibly just put service xxx restart in there.

To give details to modify the config file we'd have to know how it looks

svc [ -udopchaitkx ] services DESCRIPTION
services consists of any number of arguments, each argument naming a directory used by supervise(8). svc applies all the options to each service in turn. OPTIONS

After it stops, do not restart it. -o Once. If the service is not running, start it. Do not restart it if it stops. -p Pause. Send the service a STOP signal. -c Continue. Send the service a CONT signal. -h Hangup. Send the service a HUP signal. -a Alarm. Send the service an ALRM signal. -i Interrupt. Send the service an INT signal. -t Terminate.
