I don't believe this.  I can't help with configuration, but I very much
doubt this is the problem.

No.  *Interfaces* have IP addresses, not computers.  Your lan and modem
*must* have different addresses.  You have to make sure that the modem
is the default route for unrecognised addresses (i.e. for all the
Internet except your local intranet).

Definitely so.
