Establishing an OpenVPN tunnel from a system on the LAN to a server on WAN

Greetings,

an industrial Helmholtz router on the LAN is trying to establish an OpenVPN tunnel to a central server on the Internet, to no avail. A Helmholtz connection test program is telling us that a connection to the central server can be accomplished, but a tunnel cannot be established. Since the Sophos XG also uses OpenVPN for home office users, I was wondering whether this might actually the problem?

Many thanks in advance,

Stephan

Hello Stephan Gilbert,

Thank you for reaching out to the community, which Product, model and firmware version you are using for the Sophos VPN ?

Hello Stefan,

the open VPN function on the firewall (regardless of whether it is SG or XG/firewall) should not interfere with a client's VPN tunnel.
Rather, it is the port used which may be disturbed by web filters or SSL interception.
First, i would check the firewall log to identify used protocol (TCP/UDP) and port.
If you own a Sophos Firewall (XG/XGS) we should move the question to the corresponding forum. (here we are at the SG/UTM forum)

Thanks! I'll investigate the logs to see if the packets were blocked. I'll try moving my question.
