How to Access ADSL Modem IP after Run PPPOE on Mikrotik?

Hi
i set my adsl modem on bridge mode, and then connect with PPPOE on mikrotik to Internet.

Question is How to Access ADSL Modem IP after Run PPPOE on Mikrotik?
because ethernet of mikrotik router side to modem, have not ip address

please help me
thanks

Put an IP address on that ethernet port and make sure it is inside the range used by the modem and outside the
range used on your LAN.

it’s not possible
because ethernet who connect to PPPOE should not set IP address
this ethernet give ip from my ISP (NAT)

That is incorrect!
The ethernet port can have a local IP address like 192.168.0.2/24 with your modem having address 192.168.0.1/24, for example.
The IP address given by the ISP is not on the ethernet port, it is on the PPPoE interface in the router.
Besides that, it is no problem at all to have more than one IP address on an interface.

my modem ip range 192.168.2.0/24

mikrotik ether 1 ip = 192.168.2.2
pppoe output set on ether 1

ether 1 = pppoe output
ether 2,3,4 in local bridge
local bridge ip range = 192.168.77.0/24

my computer give DHCP ip from local brige
i Correctly access to internet But still i didn’t access to modem ip (192.168.2.1) !!!

You will either have to add a route to 192.168.77.0/24 via 192.168.2.2 in your modem, or add
a Masquerade rule to your MikroTik (in IP->Firewall->NAT) with outgoing interface ether1.
