Privat VPN for Lan Gaming

XxSARGExX

Hello @all

I am new into this whole VPN theme. But i have basic knowledge about Networks and how they work.

I have set up a Windosws 2019 vServer with an OpenVPN Server Config, I used the example file from github to start into this.

My idea was it to build up a little VPN Gaming server so that every client can host for example old lan Games without to enter an ip adress of the host (Boradcasting)

i startet with an basic Server and Client Config to connect the clients with the server and the clients with the clients.

proto tcp4-server
dev tun
tls-server
tls-auth "C:\\Program Files\\OpenVPN\\easy-rsa\\keys\\ta.key" 0
tun-mtu 1500
tun-mtu-extra 32
mssfix 1450
ca "C:\\Program Files\\OpenVPN\\easy-rsa\\keys\\ca.crt"
cert "C:\\Program Files\\OpenVPN\\easy-rsa\\keys\\ServerVPN.crt"
key "C:\\Program Files\\OpenVPN\\easy-rsa\\keys\\ServerVPN.key"
dh "C:\\Program Files\\OpenVPN\\easy-rsa\\keys\\dh4096.pem"
server 10.10.10.0 255.255.255.0
client-to-client
keepalive 10 120
cipher AES-128-CBC
comp-lzo
persist-key
persist-tun
client-config-dir "C:\\Program Files\\OpenVPN\\config"
verb 3
route-delay 5
route-method exe
push "route 192.168.0.0 255.255.255.0"
route 192.168.182.0 255.255.255.0

remote xxx.xxx.xxx.xxx
client
port 12345
proto tcp4-client
dev tun
tls-client
tls-auth "C:\\Program Files\\OpenVPN\\config\\ta.key" 1
remote-cert-tls server
tun-mtu 1500
tun-mtu-extra 32
mssfix 1450

ca "C:\\Program Files\\OpenVPN\\config\\ca.crt"
cert "C:\\Program Files\\OpenVPN\\config\\ClientVPN.crt"
key "C:\\Program Files\\OpenVPN\\config\\ClientVPN.key"

cipher AES-128-CBC
comp-lzo
persist-key
persist-tun
verb 3
mute 20

Every client can ping each other and we can play games by connection directly to the ip adresses of the hosts.

What do i have to edit to enable an UDP Broadcast to play older games in LAN without any option to connect direct to the Ip adresses ?

Thanks in advance and greetings from german 🙂

You need setup server bridges so it can broadcast .what you are doing now is tun . It is not working for you .

Research tap setup openvpn so there is more gelp to get you start

Thanks for the information.

Have read some guides and tutorials about Bridging and now the Server ist running as it should be.

Have already tested it with one friend and 2 games.

Just one thing confueses me. Ive got this Error messages in my server log coming from the clients. "read UDPv6: Unknown error "

new server config.

port 1194
proto udp
dev tap0
dev-node "ServerVPN"

client-to-client
keepalive 10 120

On the Server i set up my TAP to 10.8.0.4 255.255.255.0
