windows - Can't access the internet when connected to OpenVPN server

I have recently installed OpenVPN on my windows 2003 server.
Once someone is connected to the server, they do not have internet access.

• My network is on 192.168.1.1


• my server is on 192.168.1.110


• I am using the dd-wrt firmware


• I have enabled port 1194 for 192.168.1.110 on the router


• Routing and Remote Access is disabled


• I have 2 Tap-Win32 Adapter V8(s) on my windows 2003 server


• I have tried setting this line to 192.168.1.1 and also my isp's dns servers
  push "dhcp-option DNS 192.168.1.1" # Replace the Xs with the IP address of the DNS for your
  home network (usually your ISP's DNS)




• I have created an advanced routing Gateway in dd-wrt

  
  
  

   Destination LAN NET: 192.168.10.0
   Subnet Mask: 255.255.255.252
   Gateway: 192.168.1.110
   Interface: Lan & WLAN
  

I have followed this website exactly: http://www.itsatechworld.com/2006/01/29/how-to-configure-openvpn/

EDIT: I just tried to connect through the cmd prompt and get the following subnet error - potential route subnet conflict between local LAN [192.168.1.0/255.255.255.0] and remote VPN [192.168.1.0/255.255.255.0]

My server file looks as follows:

local 192.168.1.110 # This is the IP address of the real network interface on the server connected to the router

port 1194 # This is the port OpenVPN is running on - make sure the router is port forwarding this port to the above IP

proto udp # UDP tends to perform better than TCP for VPN


mssfix 1400 # This setting fixed problems I was having with apps like Remote Desktop

push "dhcp-option DNS 192.168.1.1"  # Replace the Xs with the IP address of the DNS for your home network (usually your ISP's DNS)

#push "dhcp-option DNS X.X.X.X"  # A second DNS server if you have one

dev tap

#dev-node MyTAP  #If you renamed your TAP interface or have more than one TAP interface then remove the # at the beginning and change "MyTAP" to its name


ca "ca.crt"  

cert "server.crt"

key "server.key"  # This file should be kept secret

dh "dh1024.pem"

server 192.168.10.0 255.255.255.128  # This assigns the virtual IP address and subent to the server's OpenVPN connection.  Make sure the Routing Table entry matches this.

My client1 file is as follows:

proto udp

remote my-dyna-dns.com 1194  #You will need to enter you dyndns account or static IP address here. The number following it is the port you set in the server's config

route 192.168.1.0 255.255.255.0 vpn_gateway 3  #This it the IP address scheme and subnet of your normal network your server is on.  Your router would usually be 192.168.1.1
