I'm Not able to put on the DHCP on the modem.
I think my provider changed the firmware of my modem.
And when i reseted the modem it got in to no-DHCP modes.
I try to call them but they said it was not possible to put on DHCP on the modem.
So how do I need to configure my router to be able to loopback when using DHCP from the router.
