Hi, I have a problem when I try to configure my Deco x50 with PPPoE (ISP with optic fiber). My ISP uses VLAN 50 for internet (priority 0).

Deco x50v1: 1.6.3 firmware

There are 2 cases:

Case 1 (It's working successfully):

ONT (bridge mode) connected to x50, ONT is configured to tag VLAN 50.  In this case, the x50 is configured with user/pass (no configuration in "IPTV/VLAN" section).

This configuration is OK, x50 receive Public IP Address and evething is OK.

Looking in logs I see:

Case 2 (here is the problem):

ONT (bridge mode) connected to x50, ONT is configured without tagging VLAN.  In this case, the x50 is configured with user/pass and in "IPTV/VLAN" section I configured a ISP Profile with VLAN 50 (priority 0).

I tried several times and reseting Deco. Some idea?
