Hello everyone! I'm facing a serious problem with my new ER7212PC v2.0: I simply can't access my ODI DFP-34X-2C2 STP stick at all. The default access IP for the ODI DFP-34X-2C2 is 192.168.1.1, which gives access to a web interface with a series of settings such as LOID, LOID Password, PLOAM Format, PLOAM Password, GPON SN, Vendor ID, software version 1, software version 2, Product class, HW version, Device serial number, MAC, MACKEY, etc. This is essential for the user to be able to clone some information from the ISP's HGU and receive authentication.

I have normal access to this web interface via Media Converter TP-Link MC220L v5.0. However, when I connect the ODI DFP-34X-2C2 stick to SFP port 1 or 2, I can no longer access the stick's web interface, although the ping (ping -t 192.168.1.1) responds normally. On the ER7212PC v2.0 I tried to set a dynamic IP and was unable to access, so I followed the logic that should work correctly by setting the static IP 192.168.1.2 and subnet mask 255.255.255.0, and in the same way I cannot access the web interface via IP 192.168.1.1, although the ping responds normally.

I see several reports of ER7212PC v1.0 users normally accessing this same ODI DFP-34X-2C2 stick by setting the static IP 192.168.1.2 and subnet mask 255.255.255.0 to an SFP port of the ER7212PC v1.0, so there was some change in the ER7212PC v2.0 update compared to version 1.0. I figured it might be a firmware-related bug, so I installed the latest beta version ER7212PC_v2_V2.1.3 pre-release (https://community.tp-link.com/en/business/forum/topic/843040), but the problem remains: I still can't access the stick's web interface via IP 192.168.1.1.

In addition to the stock firmware for the ODI DFP-34X-2C2 stick, I also tried different custom firmwares, such as those from developer Tripleoxygen: M110_V1.1.8-240408, M114_V1.7.1-231021, M114_V1.7.1-231022 and V1.9.1-240202.

How can I regain access to this stick's web interface when connected to the ER7212PC v2.0 SFP ports?

Thank you in advance.
