Give an DHCP static ip address a custom gateway?

[mikeput]

How can I a static ip address assignment a custom gateway instead of the default 192.168.0.1

I use a DHCP server on my network on Asus Merlin, I need to give the a certain device that can only be given an ip via DHCP (Roku) an ip and a different gateway to go off to a different ISP, is this possible?

Worked it out:

dhcp-mac=red,<MACADDRESS>
dhcp-option = net:red, option:router, 192.168.0.254
dhcp-option = net:red, 6, 8.8.8.8,8.8.4.4

Worked it out:

dhcp-mac=red,<MACADDRESS>
dhcp-option = net:red, option:router, 192.168.0.254
dhcp-option = net:red, 6, 8.8.8.8,8.8.4.4

Being this thread is over a year old Mike may not reply.
I didn't go all the way but on my AC1900P I went to
LAN then DHCP tab and at the bottom of that page is "manual assign".

Hi nstap,

Came across your post while at work, and I remember when I was seeking out something similar for my IP cam last year, what you are looking for is dnsmasq which controls the dhcp & dns on linux boxes or custom set-up's in the OP case.

here's a couple link's to get you started with documentation, hope it help's.

Best,
Davi
