hi,
I want to change the ip address of my Gpon TX-6610, from 192.168.1.1 to:
IP address: 192.168.0.1
Mask: 255.255.255.0

In DHCP server:
Start IP address: 192.168.0.2
End IP Address: 192.168.0.100

When i try to save and reboot, have this message:
Errno: 5017
Start IP Address is not in the same subnet with LAN IP or it is reserved IP Address. Please input another one.

Th e Gpon is connected directly to my laptop (MacBook Pro) by ethernet cable.
I tried to do the same operation from another machine, but i have the same error.
Please help me to solve this problem, because i really need to do this operation, to connect the TX-6610 to my router who is configured with IP: 192.168.1.1

Thanks fo your help.
