HS8247W: Can't change subnet mask

  Rewarded HiCoins: 1 (problem resolved)

In this screen any attempt to change the subnet mask to 255.255.0.0 results in the error:


Primary address subnet mask "255.255.0.0" is invalid.


This is strange because the mask is perfectly valid. Can someone help explain why this error is heppening?

Hi there!

Because the device supports up to 253 users access, it is recommended to set the subnet mask to 255.255.255.0.

Hi,

I don't need more than 253 users, I just need to set the correct subnet mask, so that the internal LAN will work correctly.
The LAN is 192.168.0.0/16, I need to set this up otherwise the DHCP clients are getting the wrong subnet.

hi, from the ONT side can not set less than 24 bit subnet mask, so you need to change the LAN side IP address

Thanks for your help.

To be clear, this is a device limitation and is by design?
