I must admit defeat and ask for help here. I am having issues connecting Yealink phones to the FreePBX VPN. I’m not sure where the issue is here; the phone, the firewall, or the PBX VPN.
I have a few FreePBX setups that I look after with this setup and have never had an issue after I managed to understand how Yealink handles VPN configs. The only difference here is that the VPN server is not running on its default port (1194) and running on 1195 because there is already an OpenVPN server running. The other sites have multiple external IP addresses so I have always taken one for the second VPN server with no issues. Unfortunately, I can’t use the existing server that is hosted on PfSense because it uses SSL/TLS + User Auth which the phone can’t handle. I have tried setting up an OpenVPN server on pfsense with the correct auth and it doesn’t work. Then I tried on FreePBX and still not working.
I wish I could see some kind of logs to see where the connection is getting stuck. The Yealink handset is a T46U. I have tried every version of the config file I can find online, but my current one is:
# Configuration automatically generated via Sysadmin RPM # MODIFICATIONS TO THIS FILE WILL BE OVERWRITTEN. # Generated at: Wed, 28 Jun 2023 17:34:29 +0000 client dev tun proto udp resolv-retry 60 nobind persist-key persist-tun remote-cert-tls server ca /keys/ca.crt cert /keys/client.crt key /keys/client.key comp-lzo verb 3 reneg-sec 3600 remote [IP OF HOST, Hidden from you naughty lot] 1195
I have a folder called ‘keys’ with the CA and two Client files in.
Is anyone able to share any advice on what I am doing wrong?
Thanks in advance!
