The "right" way to do this would be to listen to the routing socket, in which case you'll recieve a message whenever any interface goes up/down, renumbers, etc. This is what routed does, for example. Short of that, have natd re-check all the interfaces on a SIGHUP, or perhaps every 10 seconds or so (using ioctl(SIOCGIFCONF) to look at all the interface addresses). -Archie ___________________________________________________________________________ Archie Cobbs * Whistle Communications, Inc. * http://www.whistle.com
