Re: Help:Problems with routing
Thank you San for your advice.
Last night only I was able to deal with the problem of routing (out on
business :-() and your proposed solution and now I'am able to ping
whatever address on the internet from my client, BUT... the client is
unable to resolve the names (I can ping 195.110.96.65 but not
www.dada.it).
What should I do?
Thanks Vittorio
