# Diagnostic sonde Atlas Bolivie
Les ping depuis la sonde Atlas 23967 (https://atlas.ripe.net/probes/23967/) avec des longs paquets n'arrivent pas. On regarde une route, par exemple ver mamot.fr, depuis un ordinateur situé dans le même réseau local que la sonde (chez moi) :

On essaye ping vers le premier relai (192.168.1.1 , le routeur F660 de la marque ZTE, fourni par le FAI Entel - connexion par fibre optique), avec des paquets de taille 1000 et 2000: on perd déjà des paquets avec la taille 2000.

On essaye maintenant le ping avec le deuxième relai (192.168.101.101, j'imagine que c'est un routeur commun aux connexions de fibre optique du quartier - ses ports ouverts sont 1999 2399 3325 3998 5850 7627 24444 51103, je ne sais pas si ça aide à trouver ce que c'est), et là : il ne répond à aucun des ping avec une taille de paquets de 2000 !

Finalement, en regardant la configuration de mon routeur (http://192.168.1.1 - WAN Connection), il semble que le relai est l'IP 190.129.186.50, mais celle-ci n'apparait pas dans le traceroute... ça, je ne comprends pas.
