Mikrotik RB912 with modem MU709s in enabler mode

Hi,

Is it possible to put my RB912 with modem huawei MU709s, in enabler mode for a Cisco router?
How can i do that?

The idea is that the RB receive de public IP address and pass it to the Cisco transparently!

I have a configuration of another equipament (teldat 4G enabler) that do this. Can i replicate this in RB

interface FastEthernet0/0.1
encapsulation dot1Q 1 native
ip address 255.255.255.252
no cdp enable
!
interface FastEthernet0/0.463
! INTERFACE THAT RECEIVE PUBLIC IP ADDRESS
encapsulation dot1Q 463
ip address dhcp

ip nat outside#

ip virtual-reassembly
no cdp enable
!
ip route 0.0.0.0 0.0.0.0 FastEthernet0/0.463 dhcp

Thanks,
