Hi,
In a openvpn server log, I see the appearance and disappearance of TLS handshake error.
Vpn clients are connected through 3G routers or through ADSL box.
The server is, for now, directly connected to a DMZ without filtering rules.
My internet research seems appropriate firewall rules problems.
If no one changes the configurations of the firewall, what are the other sources of this type of error?
Currently 2 of 3 customers are connected to the VPN. The third seems to be stopped because I did not see a connection attempt in the log.
Best regards.
Yann.
