Not sure what is going on but I noticed yesterday that there are several unknown IPs on my router. When I try to access these IPs it is taking me to other peoples Routers etc. WTF

Hi.

That first image is from a Victron system.
Thank goodness you aren't an *******, you could have done some damage by changing settings.
Good on you for reporting it, a bit concerning that this sort of access was even possible.

Seriously messed up, unfortunately I can still access the settings.

Probably a demo system that has been setup but not secured. I can access the system from inside the afrihost network but not from my phone.

Had a similar issue years back on the Herotel network as well. Could seen other devices on my router too.

That is normal though. They are hosting it openly on their line.

I just going to ask out of curiosity. Is that because the OP is sharing the same NAT IP pool as these clients and therefor he is seeing their devices? Is there not some sort of mechanism in place to protect this from happening?

It's an issue with the FNO. Traffic for DHCP ISP's need to be forced to the gateway. Calix calls this security feature Mac forced forwarding. It forces all the macs of each subscriber to the Afrihost gateway and removes the ability to see each other if they are on the same vlan.

Huawei does this with clever mac acls on the olt uplinks and switches all the way to the dc.

If those security measures are implemented then you can't see your neigbours on the vlan. If not then they see each other over the FNO network before the traffic even reaches the ISP. Sadly FNO's can realistically only do PPPoE in SA.

Now that OP has the IP of that device they can connect to it but you need to know it to do that so it's normal not nat related.

So the only reason I picked up on the issue was that my subnet on my router changed to 192.168.7.1 yesterday, this seriously messed up my home assistant in general. Why do you think this subnet conflict was not an issue earlier, and why were the other IPs showing up in my client list?

*I've now been moved from DHCP to PPPoE.
