Question

After upgrading both RUT950 to 00.06.06.1 firmware:

From my LAN behind RUT950 and from its WebUI now I can`t ping or connect to any port to my second RUT950.

From any other IP ping and connect are ok. From behind any of my LANs pings and connections to outside also are ok, excl. my modems.

Iptables shows nothing suspicious, access control in WebUI - also.

What should I check next?

Hello, Leonid!

Is it possible for you to send me the topology of the network?

Or could you describe it in more details?

Best regards, Aliaksandr!

Hello, Aliaksandr!

Two LANs, each behind the RUT950 4G modem with static IP.

I had forward rules on each of modems to reach servers from one LAN to another via SSH.

On both are running OpenVPN servers to connect individual clients from WAN and from other LAN as well.

Nothing special, but even pings doesn`t work between these two modems :(

If I understand correctly, then the device behind the router cannot ping the second router?

And the first router also cannot ping the second, right?

BR, Aliaksandr!

Yep. No ping, no connect, nothing...

Ok, I get it.

Could you take a screenshots of WebUI -> Status -> Network -> Mobile page for both routers?

For security reasons, please remove the parameters IMEI, IMSI, ICCID.

BR, Aliaksandr!

Here they are :)

Thanks!

Now, could you send me to PM Troubleshoot files of both routers?

You could find them in WebUI -> System -> Administration -> Troubleshoot

BR, Aliaksandr!

How can I send PM?

Click on my nickname here, after that you will be redirected to my profile page. There opposite the "Type" should be a green button "Send private message"

No button. Should I be registered for this action?
