Modem+Router Combo Device: Syrotech SY-GPON-1110-WDONT

Hardware VersionV3.7L
SoftWare Version3.0.01-210617
The Combo Device was initially configured with Modem and WiFi settings. It is a single-band (2.4GHz) WiFi Modem+Router combo device. Its network connection strength, as well as reliability, is poor.

I have disabled the Wi-Fi, and am using the device purely as a Modem. There is a POTS device connected to the Combo device, and it is currently working (Make and Recieve Calls). I need to keep the Phone Line connected and operational.

The Syrotech Combo Device is connected to an OpenWRT Router, which also serves as a Wi-Fi Access Point.

The Combo Device is currently configured in "Route" Mode. I Need to set it up in “Bridge” Mode. Additionally, I want to ensure the Telephone remains active and operational.
The primary purpose is to eliminate the Double NAT situation.

On the Connection Status Page, it says:

Connection Info

Connection StatusRegistered, not authenticated.
This suggests the BSNL Network might not be MAC Binding the FTTH Connection with the MAC Address of the Syrotech device.

Q. 1 Does this mean ANY router (with its own MAC) could be set up in PPoE Mode without calling up BSNL and requesting MAC Reset? Or do I have to call BSNL and ask them for MAC Reset or Clone the appropriate MAC Address of the Syrotech Device in the OpenWRT Router?

Backing Up Current Settings:

Q. 2 Before changing anything, How to safely backup All Settings in case I need to revert? Moreover, How to Restore this “LastGood.xml” file properly?

There are the following options under Device Management > Config File Management:

Save current as default

You can upload and download the config file <SaveCurrDef>

And

Cancel Custom Default

You can cancel the self-custom default config file. <CancleCustDev>

(There are typo errors on the Page, which is a bit unnerving)

Below the above options, it states:

Upload: Upload custom config file. Configuration will be covered by resetting to default.

Upload As Default: Upload custom config file as default setting.

The device will auto reboot after the upload success. If not, reboot the Device to take effect.

What do the abovementioned options do?

Q.4 Choosing the “Bridge” Mode makes the PPoE Options Disappear, which is understandable. However, will Bridge Mode also make the VoIP options disappear/disable? I need to keep the Landline Active and Operational.

As evident from the screenshots, Port Binding is active on all Ports: Port_1, Port_2 as well as WLAN (SSD1).

Please advise HOW to correctly set up the Syrotech Combo device in Bridge Mode while keeping the landline alive and operational. I will configure the PPoE Credentials into the connected OpenWRT Router.

Are the following settings on the Syrotech Combo Device correct? Do they need to be changed?

  • Change Mode to Bridge Mode (from PPoE)
  • Select both IPV4/IPV6 on the IP Protocol Mode
  • Tick Enable VLAN and enter the VLAN ID provided by BSNL (160)
  • Select WHAT NUMBER (from null to 7) on 802.1p, and Why? Currently, it is set as (null)
  • MTU: 1460
  • Select INTERNET in Service Mode
  • Keep LAN DHCP Unchecked (Meaning, LAN DHCP will be Active?)
  • Port Binding - Select Port1 and Port2 and leave the WLAN (SSID1) Unchecked as WiFi is disabled.
  • NAT Type: NAT1 or NAT2 or NAT3 or NAT4 (Currently it is NAT4)
  • WHAT to enter in the LAN Settings Page: Disable or Enable DHCP Server?

On the OpenWRT Router:

Change the setting from DHCP to PPoE, and enter the FTTH Landline account and Password from BSNL.

Under Advanced settings:

  • Get IP from ISP - Enabled
  • Primary and Secondary DNS (Set Manually instead of BSNL) - 8.8.8.8 or 1.1.1.1 or something similar
  • Override MTU / MRU - Unchecked or 1460
  • Internet VLAN - Unchecked

Is the following step mandatory or can it be skipped as Connection Status is Registered but not Authenticated?

Override MAC Address - Customize MAC Address. Enter the WAN MAC address from the Syrotech Status Page from the 1_INTERNET_R_VID_160 row (not the PPPoE).

Registered, not authenticated means there is no authentication enabled on the OLT. You will still have to reset MAC for PPPoE or you can simply copy the one on the Internet profile under WAN Info.

Press Download and it will save the current config in an xml file. Use Upload instead of Upload as default to restore.

VOIP profile is separate from Internet profile.

For bridge mode, (Port 2 is gigabit and hence port bounded)

On Openwrt router (depending on version and hardware used), simply create a WAN interface and select protocol, enter username, password, select device (physical interface), MTU will be automatically discovered. Select IPv6 if you like.

Yes, you will have to override MAC.

@sloj Thanks for the simple explanation.
Will set up the Bridge Mode on the Syrotech Combo device as per your advice.
Bridge Mode will make the Combo Device inaccessible via WLAN and LAN connected via the router, Right?
If yes, how to ensure access to the Combo device? I Need to periodically check on the Tx and Rx Power as well as the Status of the FTTH Line.

I am stuck at the MAC address step in OpenWrt.
How to clone the MAC address of the ONT (Override Mac) in OpenWrt?
I have created a @Wan profile (PPPoE BSNL) and a Modem Access profile in Network > Interfaces.
However, I am unable to change/override the MAC address.

What device are configuring on? Show the devices tab in the first screenshot.
 

@sloj Here's the Devices Tab:
BSNL-PPPo-E-04.jpg


The Configure Option does not allow to change the MAC address as the field is Greyed out:
BSNL-PPPo-E-05.jpg

According to your previous advice for PPPoE handover to OpenWrt, I created a new interface select protocol (PPPoE), entered username (BSNL FTTH), password, and selected device (@wan). "Physical interface" is Device right?
 
What device is this? A mini PC or something else. I need to know the physical interface. br-lan contains which ones lan1-4, eth0 is what on the hardware, etc. Every device is different and layout is different for each device.

If I go with the first screenshot, then you need to delete alias of wan, wan and wan6, then configure wan and enter the cloned MAC from ONT PPPoE interface and save it. Then on interface tab create a new one, protocol PPPoE, device wan and the username, password. MAC shouldn't be greyed out, the default is displayed as a placeholder.
 
@sloj
It is a Regular dual-band router with 4 LAN ports. There's a Single Gigabit WAN Port to which SY-GPON-1110-WDONT ONT is connected.
The router is running OpenWrt 23.05.
br-lan bridge device seems to be the 4 LAN ports.
I do not know what is eth0. But its MAC address is the same as that of br-lan, lan1, lan2, lan3, and lan4.
The phy1-ap0 and phy1-ap0 should be the WiFi Access points. They each have a separate MAC address.
The wan device too has its own MAC address.
