How can i access the setting page for Huawei HG8240w?

Brand: Huawei
Model: ONU-HUAWEI-HG8240w
Telco: TM Unifi

Terminal IP: 192.168.100.1
Computer IP: 192.168.100.20

I can ping the router IP 192.168.100.1, but i can't access the WebUI page at http://192.168.100.1
I also tried telnet at port 23, ssh to port 22. None of it success.
I tried with LAN port 1 and LAN port 2, same result.

Thanks!
