OVPN Site to site - no clients?

[BigMikeSK]

Hello,

it all worked just fine, but after upgrading to 2.5 I have a an issue that OpenVPN Status shows 0 clients connected, but client is defintely connected. Another new issue is, that I can ping this remote client, but client cannot ping me. As I said, it all worked fine before. Are there any breaking changes that can couse this?

Thank you.

Any idea if would clean installation of the latest version resolve this issues or is something wrong with 2.5 itself?

Thanks again.

So when I try to ping OpenVPN server from client, I can see this in OpenVPN log:

IP packet with unknown IP version=0 seen

I have comression disabled on both sides so that in not the issue I guess.

@bigmikesk OpenVPN 2.5 deprecated some ciphers IIRC which broke a lot of people's working configs. I have site to site configured and I have:

Data Encryption Negotiation: Checked
Data Encryption Algorithms: AES-128-GCM, AES-256-GCM, CHACHA20-POLY1305
Fallback Data Encryption Algorithm: AES-256-CBC
Auth digest algorithm: SHA256

@kom Hi,
I think if it would be the encryption issue, I woud't be able to connect at all I guess.
