Question

Hello,

A client of mine has two sims with static IP. He called me because he wasn't able to open ports to a device, even though he got his fixed IP and was able to connect to the web.

My steps in order to fix the problem:

upgrade firmware

reset via web ui

reset with button

finally after going through, I think every setting that can affect opening ports on the router, I told him to bring a router from a different company and see if port forwarding works - it did without any issues.

I told him to bring the router to our lab.

Btw, I tried to reset the RUTX12 to boot loader menu, but I wasn't able to.

Is there anything I can do in order to troubleshoot the problem?

Thanks in advance,
Roy

Hi, Please can you share which specific ports the customer is unable to open and how it has was setup and tested ? Is the Rut accessible ? Please see if you can re-trace the steps listed for device recovery specified in this link https://wiki.teltonika-networks.com/view/RUTX12_Device_Recovery_Options.  Also, share the troubleshoot file to me as a private message to analyze further.

Thanks

I just tried to open different ports (90 and 1554) and it worked. Is it possible that ports 80 and 554 are disabled?

I followed the instructions in the link but I wasn't able to reach the device recovery page (I did reach recovery on 955/955 what problems in the past). The device does a normal factory default.

Hi,

Is the command line to the RUT accessible ? If yes, then please share the output of the following commands :

1> netstat -tulpn | grep LISTEN

2> grep -w 554/tcp /etc/services

3> grep -w 80/tcp /etc/services

4> grep -w 90/tcp /etc/services

Thanks

I managed to reset the device to recovery after several more tries.

I have a different problem now - I can open the 80 and 554, but on LAN 1 the router sometimes doesn't open the ports. On other LAN The ports open instantly, while on LAN 1 if the ports do open, it takes a while (1~2 minutes).

What can cause this problem?

Thanks,

Roy

Hi, Please can you capture the troubleshoot file during latency you observe when on LAN1 and send it to me ?

How are you testing / observing the delay in specific ports access ?

Also, please can you elaborate on the steps you are performing to open the 80, 554 specific ports ?

Thanks
