How to redirect all Internet traffic to OpenVPN Server
- by JuliaS
I have seen working solutions around the issue of forcing Internet traffic to go through the OpenVPN server but they are all done in Linux, all I want to know is how to add an entry to the route table in windows to make this happen. connectivity between the client and server is fine, my Windows 7 client can establish a connection to the Windows 2008 Server, but when established Internet traffic is still going from the local Windows 7 machine. Here are the details:
Server:
Windows 2008 Server with one NIC
OpenVPN IP Address: 192.168.0.1
Local NIC IP Address (connects the server to the Internet): 10.242.69.107
Client:
Windows 7 with one NIC
OpenVPN IP Address: 192.168.0.2
ISP allocated IP Address: 10.0.8.2 (gateway 10.0.8.1)
Server OpenVPN Config:
dev tun
ifconfig 192.168.0.1 192.168.0.2
secret static.key
push "redirect-gateway def1"
Client OpenVPN Config:
remote xxx.xxx.com
dev tun
ifconfig 192.168.0.2 192.168.0.1
secret static.key
I'm not an expert with adding routes...etc. I would be grateful if someone could let me know how to add this entry in my server/client route table.
EDIT:
Output from the client's netstat -rnv
IPv4 Route Table
