The --redirect-gateway option is brand new as of beta13.  I would start from
one of the configuration file examples on the web site, get it working, then
add the --redirect-gateway option to the client.

This option will redirect the system default gateway to the VPN tunnel (in
such a way that it doesn't create a routing loop).

The server will need to be configured to do NAT or MASQ on behalf of clients
connecting over the VPN, since all client IP traffic on the way to the
internet (such as web browsing) will pass through the tunnel first.

The other thing to think about is DNS addresses.  DNS queries by the client
will also go over the tunnel.  That means that the client must be set up to
use DNS addresses which will be resolvable by the server.
