I am new to the Teltonika gear and have an old RUT240 laying around. I am struggling to connect to the web ui via its external IP address. I have enabled both HTTP and HTTPS using ports 80 and 443 respectively. I can ping the modem via its external IP and can access the WEB ui via the LAN port. Port forwarding seems to work to a PLC on port 502. I had factory reset the router so the firewall rules are default other than the PLC one I added. I have checked and the HTTP and HTTPS rules are enabled allowing traffic. I can connect my computer to it as well and use it as a router to connect to the internet, but I am still not able to connect to the web ui via another device as its external IP.
Can anyone shed any light on what might be going on?
To troubleshoot this issue, could you confirm if your device has a public IP address? It’s possible that your ISP is assigning a CG-NAT IP address, which would prevent remote access from external networks?
Additionally, I recommend checking the remote device access wiki article here: Remote Device Access – it may provide useful insights and key points.
Let me know how it goes or if further assistance is needed.
Thanks for your reply. Yes it definitly has a public IP address as I have set up port forwarding with it to access a PLC remotely. The range of IP addresses given are 121.90...
I have another router I have been using, which is a Vodafone MachineLink 4G which is based off a Netcomm NWL-25 and I can access its webu ui using the same sim.
A bit of an update on this and it is really getting frustrating.
I have factory reset the modem and started again. With a default LAN ip, i was able to get to it remotely as well as locally. I then changed the LAN ip to suit that of my devices and I was unable to get to the modem locally, but could still remotely. I am pretty confused.
