Anyone experience disconnect on Maxis Fiber VDSL ?

that only happen when i use custom setup. where

NETIS (VLAN ID 621, map to port 2 not tagged) --> Netgear r6300v2 (dial pppoe)

this setup works fine for months, until today it connect after reboot both device. then few minutes later it disconnect and it wont reconnect. i look into the syslog. it says received disconnect command from the ISP.

then when i change the setup back to original maxis one.
NETIS (VLAN ID 621, map to port 2 tagged) --> MAXIS TP Link Archer c5v

it works fine........


issue is, the stock router sucks. i would like to use my NETGEAR as primary dialer/router. and TM NETIS as bridge. but this setup seems not working.

i already send technical to maxis, wait them call back.

can anyone verify the untagged and port map method, for non VLAN router still worked. mine connected pppoe a while then get disconnected.

the modem as bridge is the TM Netis DL4480v1

is your BTU Netis or Huawei one ?

for now i revert back using Maxis stock TP-link C5v first. plan to get router that support proper WAN VLAN tagging.

since my previous router [netgear 6300v2] the switch only support 2 digit vlan only. even change to merlin firmware [they have maxis profile option with proper WAN port VLAN tagging] or ddwrt which only show 16 VLAN only.

i think they do some remote upgrade to the BTU, or they check for specific packets with tags..... on PPPoE, i can confirm is they will send disconnect command to our modem if no VLAN tagging configured [port map method].

your router support wan vlan tagging ?

tested, and confirm.

the modify method will no longer work. maxis will disconnect when VLAN 621 is mapped to single port and untagged from modem. router that connect via PPoE this way won't work any more.

sadly have to buy new router with WAN VLAN tagging support.
