Hi there.

I have an ER706W V1.0 using Firmware build 1.1.2 Build 20240726 Rel.77184(5553), which I have been using port 1 for an RJ45 to my ISP. I have now purchased an SFP XPON module which has its own interface for programming. (See URL, https://www.hitoha.moe/odi-dfp-34x-2c2-gpon-onu-sfp/ ).

I have tried to get into this interface many times with different combinations but I cannot. The router will also not let me Telnet into port 23 and gives me the message 'Connect failed' on port 23.

Tried using Factory Settings to set up.

I have tried assigning an IP address to the adapter using its MAC address - still no use.

I have no firewall settings or any blocks on this. There is clearly nothing wrong with the router SFP interface as I have been connected through Port 1 to my ISP with RJ45 SFP since I bought it but now I need the XPON to work which I cannot do without getting into the SFP module's web interface.  

How can I solve this problem please?

Why is Telnet not working as well?  Probably a separate matter but it's a real pain.

Thank you.
