RT-AC68U unable access modem page after bridge

[rose123]

I'm trying to access the Draytek V130 status page to work after bridge.
But keep getting unable to connect to 192.168.1.1

I bridge it with a RT-AC68U 192.168.2.1 which is connect via PPPoE
All my settings is the same with my old TPLink wireless router.
All the PCs, tablets, phones have it's own IP address 192.168.2.xxx
None of them conflicting.

Before that I use a TPLink Gargoyle firmware in 192.168.2.1 able to get into the Draytek V130 status page easily without any settings, when I use any of my devices that with 192.168.2.xxx

Please help and thanks in advance.
