ORBI RBK853 Port Forwarding only works from External

Hi All, I tried searching but didn't find any threads with a solution. I just upgraded from Nighthawk RAX120 to ORBI RBK853 Mesh last night. I've setup port forwarding the same way as it was on th...

Hello pc74,

Welcome to the NETGEAR Community!

I understand that you would like to split networks for your static and DHCP devices.

Please do the following:

Use a network of 192.168.2.1 with the subnet mask of 255.0 for your DHCP devices.

Change your current network static subnet mask address to 255.0.

You can also use the IP address 192.168.1.1 with a subnet mask of 255.128 this will give you access to 126 usable devices. Then you will be able to start your second network at 192.168.1.128 with a mask of 255.128.

Best,

Kevin

Hi Kevin,
If I set each one to .255.0 network mask wouldn't that prevent the static ip and dhcp devices from being able to communicate with each other?
Thanks,
Peter

Hi pc74,

Thank you for your reply!

Both solutions provided split your network into different networks. For devices to communicate they will have to be on the same network. If you would like all devices on your network to communicate you would need to use one network address. My recommendation is to reserve the IP addresses that you would like to keep static but ensure that is it on the same network.

In your case, your network subnet mask is 254.0. That gives you a network range from .0.1 -1.168. Try changing your router's IP address to 0.1 with a 254.0 subnet mask.

Best,

Kevin

  Hi Kevin,
  Thanks for the suggestion, when I get a chance to change the default gateway of all the 20-30 devices that are on static ip I'll try changing it from 192.168.1.1 to 192.168.0.1 and see how it goes.
  Thanks,
