When this situation occurs on *any* OS I'd check the "defaut" route and/or the connectivity of the other end. You don't say what the connectivity of the other end is for the tests you've performed and it makes a difference to the ability of the pi3 to respond via the correct interface. -- David Pick Network Security Manager, IT Services Queen Mary University of London TB202, Mile End Road, London E1 4NS Tel: +44 (0) 20 7882 7079 Mob: +44 (0) 7973 379 161 E-Mail: d.m.p...@qmul.ac.uk Normal working days are Monday to Wednesday inclusive Worried about Cyber Security?
