Regardless of that, that section refers me to '3.3.4.3 Choosing a Source Address', which does more succinctly address my question. All I find upon a first read is: (b) The route cache may be consulted, to see if there is an active route to the specified destination network through any network interface; if so, a local IP address corresponding to that interface may be chosen. But, nothing in RFC 1122 seems to shed any light on a selection algorithm. At least thia RFC grants me more vectors of research; thanks again... > Lars > -- > Lars Eggert NEC Network Laboratories -- Brian Reichert <reichert@numachi.com> 37 Crystal Ave. #303 Daytime number: (603) 434-6842 Derry NH 03038-1713 USA BSD admin/developer at large
