Bad news, it doesn't work, I can obtain a link ok in the module only if I disable speed auto-negotiation, and still can't ping or ssh to the GPON.
Try ip-scan to see if anything responds...
[admin@MikroTik] > tool ip-scan interface=sfp1 address-range=192.168.1.0/24
Flags: D - dhcp
ADDRESS MAC-ADDRESS TIME DNS SNMP NETBIOS
192.168.1.10 00:06:B5:BE:11:EF 1ms
Change the sfp1 interface to 192.168.0.15 and scan 192.168.0.0/24. Repeat for 192.168.2.0/24, 192.168.3.0/24, 192.168.4.0/24 networks. I've have seen document claiming 192.168.4.254, 192.168.3.10, 192.168.1.251 to be ONT's configuration IP
You was rigth @JeanPierre, the correct IP was 192.168.2.2. After configure NAT masquerade for sfp1 I can login with user: ONTUSER
and password: SUGAR2A041
That's the good news, the bad news is I can't configure anything once logged in. Nothing is displayed about the busybox and commands like onu gtcpg
Also it runs extremely slow, even when writing, becoming apparently frozen.
In any case, it's a progress, thank you.
