Hej,

 

Can you please help me understand if this is right? Yesterday the DDNS WAN address was 98.128.142.6 and today is still the case (NOIP). However pinging from otuside, 98.128.142.1 is the address that is responding and yesterday it was 98.128.142.6. When using 98.128.142.1 I cannot access devices with port forwarding,

To better help you, may I know the version of your controller?

By the way, have there been any recent changes to your network?

You can try to re-configure the DDNS to test.

Best Regards!

The controller is an OC200 and all devices have the latest firmware.

I have a fixed public IP address from my ISP and it is connected to a WAN customized MAC Address (from internet/WAN settings)

I can ping 98.128.142.1 and not .6 however port forwarding does work (needed to get it right between http and https in some cases). I have removed and re-inserted DYNDNS and still get the router IP i.e .6 and that is also the case for an independent SYNOLOGY/NAD dns service.

For me, with limited knowledge, something wrong in the routing table where the switch is the entry ???

Just to confirm, do you mean when you ping 98.128.142.6 from outside, but the reply is 98.128.142.1?
Can you provide a screenshot to show the problem?

Normally, the next hop of the default route in the routing table shows the wan port gateway, not the wan IP, which is fine.

Best Regards!
