[SOLVED] OpenVPN not doing anything T42G V83
Hello,
I've been searching in the forum and Google about how to configure properly the server and the phone to connect using OpenVPN.

The server is running OpenVPN 2.4.4
I've created the keys using easy-rsa3 with the option nopass and using the SHA1 method
As an additional information, the server is an AWS and I've tested to connect with a local openVPN client and the tunnel and IP assignation is done correctly
OpenSSL in the server is 1.0.2k

Code:
server.conf

local xx.xx.xx.xx
port 1194
proto udp
dev tun
tls-server
ca /etc/openvpn/keys/ca.crt
cert /etc/openvpn/keys/server.crt
key /etc/openvpn/keys/server.key
dh /etc/openvpn/keys/dh.pem
server 10.8.0.0 255.255.255.0
keepalive 10 120
comp-lzo
persist-key
persist-tun
verb 3
status openvpn-status.log
;log openvpn.log

The phone is a T42G running the firmware 29.83.0.50
From the logs, the version of OpenVPN running is 2.4.2

For the phone, I've created the folder keys, put the certs inside and the vpn.cnf outside. Then using tar -cvpf (as told in the PDF from yealink) I create the tar file and uploaded to the phone. After upload, the field changes to vpn.cnf
What I don't know if the certificates have been imported correctly because I don't know if there is a way to check the files structure of the phone and search them.


Code:
vpn.cnf

client
dev tun
proto udp
port 1194
remote xx.xx.xx.xx
resolv-retry infinite
nobind
persist-key
persist-tun
remote-cert-tls server
ca /config/openvpn/keys/ca.crt
cert /config/openvpn/keys/phone.crt
key /config/openvpn/keys/phone.key
comp-lzo
verb3

As additional information, I've been writing the vpn.cnf line by line and uploading it to the phone and then rebooting to check the logs.
Errors appear only if the remote/port/proto and the keys are missing
After that, if the command is correct for OpenVPN, no error is shown except for the one below:
openvpn[1118]: OpenVPN 2.4.2 arm-unknown-linux-gnu [SSL (OpenSSL)] [LZO] [LZ4] [EPOLL] built on

I've seen the option
auth SHA1
I'm not sure if it's needed to specify the "auth SHA1" or it's the default

Hope that's all the information needed to explain my problem
Thanks in advance for any help
