Hi All,
I am new to OVPN and have just set up a OVPN as follows:

Server
armv7l GNU/Linux
Dlink NAS - DNS-327L
DNS-327L OpenVPN Package v1.01_03062016

Client Mac Osx- Catalina
client connect
openvpn-connect-3.2.2.1899_signed

I am able to connect from a variety of devices to the server but I am getting an error as follows in the server log.

Code: Select all

Note: I am setting this up under port 1199 as I have port forwarded another OVPN I successfully set up on the standard port on a mac mini which work fine. However, I would like to get the NAS OVPN solution working as this will be a better long term option.

I have no idea what the issue is but any help would be appreciated.

Just to add - I am not getting anything returned from the VPN to the client.
The VPN connect app just hangs and I suspect it is related to the server log error

What server error is that ?

Looking at this line in the server log - looks like an issue.
PUSH_REPLY,dhcp-option DNS 8.8.8.8,redirect-gateway def1,route 10.8.0.1,topology net30,ping 10,ping-restart 120,ifconfig 10.8.0.6 10.8.0.5' (status=1)

What issue exactly ?

status = 1 usually means an error

Exit status of non-zero commonly indicates an error.

That is not an exit status.

Thanks TinCanTech - I'm not saying that it is an EXIT status (server exit), just that it's probably denoting an error on the operation. As the VPN server is not returning data to my client, I was wondering if this error is the issue and how to resolve it.

Unfortunately, the OpenVPN version I'm using is quite old and is installed on a NAS and there will not be many who have installed this.

Openvpn should be reasonably compatible all the way back to v2.1
