Problem with traffic forwarding

Defozo

Hi, I want to make an OpenVPN server on my Raspberry Pi (Raspbmc).
I want to connect to it via my laptop (Windows 10) and use Internet (web browsing, skype etc.) with public hotspots.

Although my laptop connects to the server correctly, it isn't forwarding all the traffic through VPN.

Config file on my Raspberry Pi (server):

dev tun
port 1194
proto udp
ifconfig 10.3.0.2 10.3.0.1
secret /etc/openvpn/static.key
push "redirect-gateway def1"
push "dhcp-option DNS 8.8.8.8"     #serwery dns google
push "dhcp-option DNS 8.8.4.4"

Config file on my laptop (client):

##############################################
# Sample client-side OpenVPN 2.0 config file #
# for connecting to multi-client server.     #
#                                            #
# This configuration can be used by multiple #
# clients, however each client should have   #
# its own cert and key files.                #
#                                            #
# On Windows, you might want to rename this  #
# file so it has a .ovpn extension           #

What's wrong? How to fix it?

Sorry for noob question, I lack knowledge about networks.
Please help,

I strongly recommend you implement a full --server/--client with --tls-auth not a simple pre-shared-key scenario ..

HOWTO: For OpenVPN Community Edition

W10 is also very OpenVPN unfriendly so we provide this plugin for it:
