ADSL modem admin panel redirect, how to organize?

Question

network hardware

There is an ADSL modem zyxel P-660RT through which a PPPoE Bridge bridge is configured on a tp-link 1043nd router. (That is, the PPPoE link is raised not by the modem, but by the router) with DD-WRT firmware on the modem 192.168.1.1 on the router 192.168.0.1 so that there is no conflict. But sometimes I need to get access to the admin panel of the ADSL modem itself. For example, on a PC you write 192.168.0.1:8081 and you get the modem admin panel. And on 192.168.0.1 leave the admin panel of the router.
How to implement it? is it possible to?

Answer 1

Well, make a static address 192.168.1.2 and a mask 255.255.255.0 on the interface where the modem is connected. Log in to your modem at 192.168.1.1.
