Hi again,

Don't doubt yourself. You have said it did work for more than 18 months,
until the router stopped working and this cisco guy started messing around.
First: was the router getting faulty and was that the reason it stopped
working? Has the router been replaced by a new one?
Second: if you can't even get out on the internet from within your network,
they really have been messing around in your routersetup.
You have proved it that your network was setup right as it has been working
perfectly for 18 months. Your SBS should be doing the authentication for
sure, not the router. The router should pass through VPN, which isn't doing
that now obviously.
Ask for another cisco tech, preferably one that is knowing what he/she is
talking about. You shouldnot need to setup a static route. Again, it has
been working for 18 months!

Please, answer my other questions about ipconfig and if you have done the
checking on your networkbinding and regedits. Just to rule that out.
