Hi all,

I have the following setup: -Huawei HG8147X6 modem, given by my ISP (not allowed to change it) -another modem from another isp, irrelevant in this scenario -tplink omada ER605 router (for handling the 2 WAN-s) -lot of switches and servers

Connections:

HW -> Omada WAN Other modem -> Omada WAN2

Omada -> switches -> servers

On the HW router, the Omada router has a static IP, and port 22 forwarded to it

On the Omada router, the SSH server has a fixed ip, and port 22 forwarded to it.

From the Omada router subnet, I can ssh to the ssh server From the HW’s subnet, I can ssh to the ssh server (using the IP of the Omada router) If I remove the Omada router, I can ssh in from the public internet.

Does anyone have an idea, what’s wrong?
