openvpn compatible with Grandstream phones

The original script was modified to be compatible with the Grandstream phones.

Modifications:

Routing of all traffic through the VPN has been disabled.

;push "redirect-gateway def1 bypass-dhcp"

TLS, tls-crypt, or tls-auth authentication disabled.

;tls-crypt tls-crypt.key 0
;tls-auth tls-auth.key 0

The log was enabled 🙂

log /var/log/openvpn/log.log

Usage

First, get the script and make it executable:

curl -O https://raw.githubusercontent.com/jaimey/openvpn-install/master/openvpn-install.sh
chmod +x openvpn-install.sh

Then run it:

./openvpn-install.sh

You need to run the script as root and have the TUN module enabled.

The first time you run it, you'll have to follow the assistant and answer a few questions to setup your VPN server.

I recommend:

IPv6 support = no
Protocol = UDP
DNS = Google
Compression = no
Customize encryption settings = no
