HUAWEI Router tries to manipulate HTTPS connections?

At home I use a HUAWEI Router (Huawei B528s-23a), the default device which my provider recommends.

In last days I got often a certificate error when opening a website which was obviously not the routers page.

In Safari for example:

Safari: certificate is not trusted

It’s seems that the router answers the SSL-Connection instead of the page I wanted to open. Is there any explanation for this strange behaviour?

Setup Ubuntu as a router with Mesh, 4G, OpenVPN and WAN failover

I’m looking for advice on a rather complex Ubuntu 18.04 setup.

Primarily the router will just talk with other “nodes” on a local network using mesh and backhaul ‘internet’ data through 4G. If mesh is unavailable it should use 4G to talk to another node’s 4G for all traffic. This means all routers need to ‘listen’ on 4G in case another node is sending this way. Additionally, if a node does not have 4G but does have mesh is should use the mesh to connect to another node and use that particular nodes 4G connection. I have attached a few diagrams which hopefully make this more clear. In order to connect the 4G connections together we intend to use OpenVPN (server is already setup and configured).

The single-board computer and transceiver hardware is:

Gateworks GW6200 with a 2.4Ghz transceiver (wanted as a local mesh radio) and Sierra Wireless 4G modem (for a WAN connection).

Image for all connected noted. The primary connection is mesh with 4G failover

A single mesh link is broken so AV1 will be used to route traffic between AV2 and AV 3. 4G is still used as some data is sent to the internet and only local data is sent over the mesh

Here mesh only exists between two nodes to AV3 gets all data sent and received via Wifi until it is back within mesh range.

Here AV1 has lost 4G signal so it uses it’s nearest mesh node to sent any internet connections and local traffic over the 4G tunnel

My PC is seemingly hogging all the bandwidth from my router, won’t let the wifi users get any bandwidth [on hold]

It wasn’t happening until just a few days ago, so I don’t think it’s the fault of the PC, seems like the router is dying, but I cannot tell for sure How do I make the router balance the bandwidth between my PC and the wireless instead of dumping it all on the computer?

My router is getting port scan attacks

My internet suddenly cut out yesterday, i checked the router and it looked like nothing is wrong. I looked at the logs and i see this

2019-08-18 12:50:39 Security Warning Detect UDP port scan attack, scan packet from 212.2.127.253 2019-08-18 12:43:19 Security Warning Detect UDP port scan attack, scan packet from 212.2.96.53 2019-08-18 03:59:04 Security Warning Detect UDP port scan attack, scan packet from 212.2.96.53 2019-08-17 19:08:37 Security Warning Detect UDP port scan attack, scan packet from 212.2.96.53

When every attack happens my internet cuts out so how do i stop it?

Router security IP and Mac

There was no power outage nor was the router power disconnected but the entire history of the Mac and IPv4 addresses has been reset and is no longer on the router login and password for your device at 192.168.0.1.

  1. Has it been hacked or is there anything that’s not out of the ordinary other than a power outage or manually disconnecting that would cause that?

  2. Is there any way for me to recover the history including the list of Mac Addresses that connected to the router?

Thanks

Are the security basics of a non-wifi router different from securing your desktop?

I have studied much about securing a desktop from enabling firewall to browsing internet safely among other things. I also know that many steps can be taken to improve the security of wifi routers. But if I am using a non-wifi router or a usb dongle with wifi turned off, are there any steps I can take to secure that router? Or is a non-wifi router secure?

I have read about web cams that are vulnerable and can be hacked so what about routers? Can you give me an introduction? How can I find out if my router has any vulnerabilities?

I am getting a message that this question appears subjective so I will tell you that basically what I am asking is: how does router security work?
