How to get into the router settings from a different subnet?

Question

D-Link

The first router in the apartment is Mikrotik. PPPoE provider cable in port 1. The second, third, fourth port in the first bridge, the Internet hangs on them with the subnet 192.168.1.0/24. The fifth port is in the second bridge, it has IP-TV in conjunction with Eth 1. The second router: D link dir 620 where LAN 1,2,3,4 are also combined into one transparent bridge. From the fifth port of Mikrotik, a patch cord is plugged into the first port of the long line, IP-TV set-top boxes are connected to ports 2,3,4 of the long line. I lost control on D-link. It does not respond and the webmord is not available. His ip is 192.168.1.100. How to get access to the link when connected via Mikrotik? You can simply set up Wifi for a long time and connect directly, but the desire to do it right.

Answer 1

the Internet hangs on them with the subnet 192.168.1.0/24

does not converge, one contradicts the other

Answer 2

Hang on the second bridge ip from another network (for example, 192.168.2.0/24) and configure dlink's address from the new network, well, write the address of the Mikrotik as a gateway (or nativate connections towards dlink)

Answer 3

As noted above, your addresses intersect. If I understand correctly, you are going to use dlink as a switch for multicast traffic. You need to do the following, connect the dlink WAN port to the 2-4 port of the Mikrotik, so you will get access to the d-link web face at 192.168. muzzle from this port) and just connect the bridge from the remaining dlink ports to the 5th port of the Mikrotik, you do not need to assign an address to this bridge, turn off the dhcp server. As a result, you should get a switch from a long line with a dedicated port for its administration.
