RUT955 not sending data via LAN

Hi,
i have around 70 RUT955 routers and recently I started observing weird behaviour.
We using those routers to give mobile connection to self-service kiosks.

RUT955 with Simcard → connected via LAN to PC, providing internet connection.

I have started observing, that on some machines the web-based GUI is not loading, however the RUT955 was receiving bandwidth (seen it via RMS)

So I went to machine and connected to PC and router.
My observation is:
Ping from router to 8.8.8.8 - is working
ping from PC to 8.8.8.8 - not working
tracert from PC to 8.8.8.8 not working (not even one jump)
ping from PC to router is working

FW. 07.05.4

I have also available a troubleshooting file

Hello,
What is the output of:

ip -4 rule show

on the router ?
Regards,

It wont let me go to CLI, because I don’t have some sort of certificate.
GUI CLI SAYS “TO ACCESS CLI YOU NEED TO ADD CERTIFICATE ACCEPTION TO YOUR BROWSER!”

Could you try with ssh (putty, openssh …) ?

Ok, i was using the GUI name/password for device CLI from RMS. after used /root / pwd is working.

This is the output for

IP -4 rule show

Try this command:

ip -4 rule delete $(ip -4 rule show | grep 2062 | cut -d: -f 2)

and restart the ping.
What is the default route on the PC ?

I was able to find another router with the issue:

In this case, when it is in this state, the IP -4 rule show is not working

Does the ping to 8.8.8.8 from the PC works if the rule 2062 is deleted ?

Hello,

Here are some steps you can take to troubleshoot and identify the issue:

  • Make sure that failover is disabled.
  • Check the firewall settings on both the router and the PC to ensure that they are not blocking outbound traffic.
  • Make sure the default gateway is set to the IP address of the RUT955 router.
  • As you mentioned, you are using firmware version 07.05.4. Try to update to the latest firmware RUT955 Firmware Downloads - Teltonika Networks Wiki it can help solve the issue.

Best Regards,

Marija S.

Happened again. I tried to delete the rule 2062 and tried the ping again. Did not work. Only thing what helps at this stage is reboot router.

Blockquote Marija

I have updated the FW to : * Firmware version RUT9_R_00.07.06.1 couple of days ago.
Failover is turned off from beginning.

In the topology network it does not see any devices connected:

Hostname (Vendor) IP address MAC address Type Interface
There are no devices

on the all 68 PC we use the same Windows image with default gateway for the routers.

I have setup autoreboot everyday at 2:00 AM
This happened after the reboot.

Hello,

Here are some options you can try:

  1. Utilize a different LAN (end) device.

  2. Temporarily disable the firewall for testing purposes using the command /etc/init.d/firewall stop (Don’t forget to re-enable it later with the command /etc/init.d/firewall start)

  3. Please provide the output of ipconfig /all command, specifically for the interface connected to the router.

  4. Share details of your PC’s default route information please, specifically the part shown in the screenshot. You can obtain this information using the command ROUTE PRINT

  5. Conduct a packet capture using Wireshark to verify if you are indeed not receiving any packets.

Best Regards,
Marija
