Pour les pings, ils sont confirmés par le second PC.
Je fais le nslookup sur le pc portable et je fais le ping sur le pc donc les navigateurs sont bloqués.
Plus j’essaye, plus je me dis que le firewall se met en route ou qu’un truc fait office de firewall sur le PC. Pour essayer, j’ai ajouté une redirection sur mon routeur Linksys pour les 1024 premier ports.

RPC
OPEN! (Remote Procedure Call) This impossible-to-close port appears in most Windows systems. Since many insecure Microsoft services use this port, it should never be left "open" to the outside world. This port has been exploited to send "Messenger Spam" pop-ups to Microsoft windows users. Since it is impossible to close, you will need a personal firewall or NAT router to block it from external access. Do it soon!

Net
BIOS
OPEN! As you probably know by now, the NetBIOS File Sharing port is one of the largest security holes for networked Windows machines. The payoff to Malicious hackers from finding open Windows shares is so big that many scanners have been written just to find open ports like this one. Closing this port is not difficult and it should be a priority for you!

OPEN! This impossible-to-close port first appeared on Windows 2000 and was carried over to Windows XP. Since several insecure Microsoft services use this port, it should never be left “open” to the outside world. Since it is impossible to close you’ll need a personal firewall or residential NAT router to block this port from external access. Do it soon!

Il n’y a pas de firewall pour bloquer le traffic entrant à priori d’après ce que je remarque. Mais, je ne peux pas sortir
