Mikrotik LHGG + Router Zyxel M904 (WAN)

RouterOS General

Hi everyone, my main problem is accessing the network where the Zyxel router is connected from outside.
I state that I have a dynamic public IP, and before when I didn’t have the Mikrotik, but only the Zyxel I did it easily.

I used various NAT settings from the firewall/NAT menu, but to no avail.
from the outside I can access the mikrotik, deactivating the fifth firewall entry.

Then I noticed that from zyxel I can “ping” on mikrotik and access it. While from the microtik I can’t ping Zyxel and therefore I can’t log in.

I attach a photo, for me what is local is everything inside the blue box.

I, from PC1 with IP 192.168.1.2, open the mitik winboard.exe app, or via the web and access the mikrotik board. From there I have many tools available, including ping, if I ping 192.168.1.1 it gives me a timeout.
that’s why I deduced that I don’t access zyxel from mikrotik.
always from here obviously if I pin google.com or 8.8.8.8 or something else it works correctly.

while if from PC1 windows I ping 192.168.188.1 the ping is successful.

Thank you

The Mikrotik device won’t have route to the Zyxel LAN,192.168.0.0/?, network, unless you have specified it.

So on the Mikrotik device, you need to set a route to the Zyxel lan, through the Zyxel WAN address.

Additionally, the Zyxel router is likely doing NAT and Firewalling on the LAN interface, and you will need to disable or modify both in order to reach the LAN address of the Zyxel router. But this is a question for a Zyxel forum.

How can I do or verify this?
