I have just taken delivery of a RUT241 LTE router. I have plugged it in and connected to it, replacing my EE WiFi mini, and my OpenVPN connection has stopped working. The OpenVPN connects but no traffic will pass.
Just for clarity, I have the OpenVPN client on my laptop and it’s connecting to an OpenVPN service on a Netgear router at a remote site.
Does anybody know what I need to do to get this working? As I understood it, this OpenVPN traffic passes over HTTPS and should be transparent to the RUT241 and so I didn’t expect to have to make any configuration changes on the RUT241.
In a default way, any traffic passthrough easily if a connection appears but no packet is sent into to tunnel, maybe there are other routes on your PC.
You can connect to route CLI over SSH, and run this command:
Tcpdump host x.x.x.x – where x – is ip of the destination server, if the packet appears that also means all is good with the connection and data flow through.
Tcpdump, you need to download from the package manager here System->Package Manager:
Logread – command can be used in CLI mode, for example, logread -f | grep openvpn,to list all appendig logs for openvpn service.
However, try to debug step by step:
Check OpenVPN Logs: Examine the OpenVPN logs on both your laptop and the Netgear router to see if there are any error messages or clues about the connection issue. This will help you identify where the problem might be occurring.
Port Forwarding: If the Netgear router is behind the RUT241, you may need to set up port forwarding on the RUT241 to forward the OpenVPN traffic to the Netgear router. OpenVPN typically uses UDP port 1194 by default. Check the RUT241’s user manual or web interface for port forwarding options.
Firewall Settings: Check the firewall settings on the RUT241 to ensure that they are not blocking OpenVPN traffic. If there are any firewall rules, make sure they allow traffic on the OpenVPN port.
DNS Settings: Ensure that the DNS settings on the RUT241 are configured correctly. OpenVPN might require proper DNS resolution for the remote site. Double-check the DNS settings on both the RUT241 and your laptop.
Firmware Updates: Check if there are any firmware updates available for the RUT241 LTE router. Updating the firmware may resolve known issues and improve compatibility.
Contact Support: If the issue persists, reach out to the technical support of the RUT241 LTE router or the OpenVPN service provider for assistance. They may have specific guidance or solutions based on the configuration.
Remember to make any configuration changes with caution, and document the changes you make for future reference. If possible, backup the current configuration before making any adjustments.
