Untag on HG850a is possible but the IPTV wouldn't work by connecting directly through HG850a.

If IPTV not required then you can do that by accessing through telecomadmin superuser.

root user is not superuser by default

Can't recall how I did the untagging hmm... it has been quite awhile since I last access to HG850a... I will login shortly to check it out about the port untag...

Maybe ywkwy is right, I probably did it with telnet...

If you wish to setup PPP client and ISA server, you can try by setting VLAN ID to the designated internet port... Just do a Wireshark trace over that port to make sure VLAN: 500 (I'm not using Maxis FTTH) is tagged along the packets... technically it should work...

Okay, I have to take back my word... untagging only can be done through telnet.

Now, do it at your own risk... FYI, I'm testing it with Unifi. It should be straight forward to identify your own Maxis VLAN ID.

I've used fe3 for 'untagging' testing purpose...

1) Telnet to HG850a with 'root' user

2) display lswinfo


You should get all fe1-fe4 (LAN1 - LAN4) tagged with VLANID 1/209/400/500/600

3) set fe3 as untag mode


4) set fe3 NativeVlan as 500


4) VLAN ID 1 [fe3-remove] / VLAN ID 500 [fe1-remove] [fe3-add]


5) You should see the following with 'display lswinfo'


Now, take any non VLAN supported router (basically any home router), set PPPoE with login and password, try to dial... You should able to connect and get IP....

If it success, remember don't forget to save configuration @ HG850a... so any router without VLAN tagging is supported...

For Unifi, still failed connect IPTV directly through HG850a... hopefully someone is able to do it...

I've solved my last puzzle!!! Wow... Gotta thanks everyone who dig up my interest with HG850a again!

To setup IPTV for Unifi)

Continue from Step 5

6) Set fe4 as untag mode


7) Set VLAN 600 as native VLAN for fe4


8) VLAN ID 1 [fe4-remove] / VLAN ID 600 [fe4-remove] [fe4-add]



9) display lswinfo


Now, Internet-LAN3 & IPTV-LAN4

We have everything by connecting Internet/VoIP/IPTV to HG850a directly as HUB...

Don't think they authenticate based on MAC address because I had my HG8240 successfully configured to replace HG850a.

Try to open up the saved configuration with notepad/browser and look for the field as below:

<PassWord PassWord="0000123456"/>

PassWord is the optical authentication between Huawei ONU & OLT (not too sure about other brand though).

What you can do is, reset the new HG850a to factory settings, and insert the PassWord through web interface by using "telecomadmin" username then save and reboot the ONU.

If you stay in PJ area, I wouldn't mind lending you the HG8240 for you to test it out...

I think HW Rev makes diff... that's why it's better restore all the configuration one by one...

Bringing your unit to friend's house will not work because ONU password only tie to the OLT you are connected to...

Idea... you may have to login to the Alu ONU to take a look at config.

Have extra Huawei ONU if you interested to try it out!

Can't recall... not at home atm.... can you check the command from '?' ?

Okay, didn't know save not working... I'll check it out and get back to you...

We may have joined LYN before Jan 2003, haha... do you remember the DB crashed n they have to rebuild the DB.

Btw, I haven't try it yet... n will probably try it by tomorrow. I think you are right, the saved config might not contain the include port configuration so worst case scenario, we can add the scripts on startup

I'm afraid to say there isn't any way to write it to init script as the MTD block is read-only unless someone is able to compile a firmware for it...

Don't think I'm able to do anything for the startup script... sorry about it...

So now they are offering HG8240w as all-in-1 device including Wifi?
