Set gateway without set network

RouterOS General
1

Hi,
I want to set mikrotik eth1 with the following settings

IP addr: 51.75.236.xxx
Netmask: 255.255.255.255 / 32
Gateway: 192.168.4.1

The 51.75.236.xxx is the public IP and the 192.168.4.1 is a failover modem that works as a gateway.
First i would like to know if i can set the gateway (0.0.0.0/0 192.168.4.1) without set a this network in the Address list?
Secondly if i can set these through terminal

Thank you in advance

You can do this with point to point addressing:

/ip address
add address=51.75.236.xxx/32 network=192.168.4.1 interface=eth1
/ip route
add dst-address=0.0.0.0/0 gateway=192.168.4.1

And if device with 192.168.4.1 has similar config, i.e. will look for 51.75.236.xxx at right interface, it will work.
