Qualcuno sà aiutarmi?

[Raoul]

Ho una LAN con 8 pc, linea adsl alice con ip dinamico, router cisco 827 che fà da gateway.

rete:
gateway 192.168.0.254
pc1 192.168.0.1
pc2 192.168.0.2
ecc....

dns
212.216.112.112
151.99.151.1


Aggiungo altri 2 pc alla mia LAN ma questi vanno solo su google effettuano la ricerca ma non carica i siti.

www.libero.it lo raggiungono, ma altri tipo virgilio.it ebay.it ecc...mi scade la pagina.


Da cosa dipende?

Ho cambiato cavi, dns, ip interni, schede di rete ma non ne vogliono sapere di navigare.

Il router potrebbe ostacolare questi due pc ad uscire su internet?

Mah, così ad occhio non mi pare sbagliata..togli "mtu 1942" su "interface Dialer1" e vedi...hai provato a sniffare il traffico? Traceroute? Telnet sulla 80?!

prova a togliere dal dialer
