Model: ER605 (TL-R605)  
Hardware Version: V2
Firmware Version:

Hello,

Due to the high cost of a public IP from my ISP, I opted to purchase a VPS and configure an OpenVPN server to connect my ER605 using the OpenVPN Client.

However, I'm facing an issue as the OpenVPN Client on the ER605 doesn't seem to work.

Unfortunately, there are no logs available in the ER605 GUI, making it challenging to pinpoint the problem.

Additionally, when I try to access the VPN logs through SSH, I am unable to do so.

I have checked the VPS logs, but there are no signs of router login.

 

The .ovpn file I imported to the ER605 works perfectly fine on two other computers and a QNAP server, indicating that the configuration is correct.

 

ER605 has the latest firmware installed.

 

If anyone has any ideas on how I can troubleshoot and identify the problem, I would greatly appreciate it.

 

Thank you in advance.

Hi @Stachulec 

Thanks for posting in our business forum.

What's your OVPN encryption? As a matter of fact, ER605 built-in OVPN is adapted to OVPN version 2.4 or older. Can you please verify the version of your OVPN on your VPS?

OpenVPN server version: 2.6.1.

 

I am unable to locate the information regarding the supported version in the manual.

Hi @Stachulec 

If you have removed the sensitive lines, then it would be okay to post it here. If not, please remove your public IP, etc..

I briefly went through it. I found several things that we don't support currently.

OpenVPN server version: 2.6.1.

 

We don't support GCM and OVPN versions above 2.5. Please consider changing them to an adaptive one. 2.4 or older version and non-GCM cipher.

Meanwhile, I record what you reported for the dev team.
