BSNL FTTH Syrotech bridge mode - working configuration

[youbarajsha]

I am trying to setup Syrotech router in bridge mode with my TP-Link ER605 Omdada router. I have seen in the forum people using it successfully, for me I keep getting PADI times out error in the ER605 notification.

Generally its only the User ID, Password and VLAN and MTU details that are required to set it up correctly, but despite of multiple attempts, I am unable to get it working.

So far I have tried the following, but all in vein

1. Deleted the current working internet PPPoE config from my syrotech and setup a new profile in bridge mode with following settings for profile

• Selected bridge in MODE
• IPV4 in IP PORTOCOL MODE
• VLAN provided by the ISP (same as working Route mode VLAN)
• 802.1p set to 7
• MTU provided by ISP
• Turn off LAN DHCP set to off (unchecked)
• Service mode INTERNET
• Port binding to PORT1 (and yes port1 is connected to the WAN in my Omada router)

End Result - PADI times out error (meaning moden is not able to contact server and get a response). My ROUTER is configured with User ID and Password and MTU and VLAN same as Modem

2. Deleted the current working internet PPPoE config from my syrotech and setup a new profile in bridge mode with following settings for profile

• Selected bridge in MODE
• IPV4 in IP PORTOCOL MODE
• VLAN is unchecked
• MTU is set to default of 1500
• Turn off LAN DHCP set to off (unchecked)
• Service mode INTERNET
• Port binding to PORT1 (and yes port1 is connected to the WAN in my Omada router)

End Result - PADI times out error (meaning moden is not able to contact server and get a response). My ROUTER is configured with User ID and Password and MTU and VLAN same as Modem

I have tried other permutation combination (desperate attempts)
1. Used the MAC address of the bridge in the router - same PADI error
2. Used Static IP (yes I have static IP provided by ISP) - Unable to connect to WAN error
3. Used the IP6 settings along with IP4 - same PADI error


Can some one help me with a working configuration (what all is being set on the Modem and Router end to work), so that I can revalidate if all my settings are correct. Not sure if BSNL has stopped the bridge mode configuration to work.

The only working model right now for me is the Dynamic IP setup in router and connected to Modem, but this is leading to double NAT, as such I have 30% speed drop plus DNS errors popping multiple times for which I need to do IP release and renew every now and then.

I know this should not be such brain wracking, but I am trying to narrow down to the reason so that I can either go back to ISP with what I need in terms of settings or set things right in the router to make it work.

Regards,
Y

BSNL has newly introduced PPPoE MAC address authentication. So, when you change the device from which you do PPPoE connection the MAC address needs to be copied or you have to ask BSNL to reset the MAC address.

I have tried all MAC but still unable to connect, keep getting sending PADI error. So far I have used following MAC addresses
MAC from the route internet mode from Status-->WAN Connection Info page
MAC from the bridge internet mode from Status-->WAN Connection Info page
MAC given on the back of MODEM
MAC for WAN given on the back of MODEM

Try this, since you have defined VLAN in ONT, don't use VLAN again in the router.

I tried that too, but its not working. Which MAC should we be using, the one on the ONT back side or on the status page (there are four WAN's for me, two on the backside of ONT and one for Bridge and One for the active PPPoE)? The ISP guy is pretty handy with me who manages OLT (but not that great in terms of networking), should I ask him to register the MAC of my new Router in OLT?

The one used for PPPoE as seen in the status page. You may have to ask them to reset if copying isn't working. And the reset isn't on the OLT, PPPoE doesn't happen on the OLT.

I do have the option to Customize the MAC address (not clone) in my TP-Link Omada router, but despite of entering the MAC for the PPPoE, it not working. I keep getting the PADI times out error.

Are you using PPPoE session on ONT too? If yes, you can't do that. Is there any more detail in the logs?

 

[youbarajsha]

Nothing else in the log, it just says PPPoE username@ffth.bsnl.in failed to connect to the server because sending PADI times out. I have completed deleted the working PPPoE profile from the ONT and kept it in bridge mode.

Then I guess you have to ask BSNL to reset the MAC address used for PPPoE. I have seen another user had a problem with PPPoE when copying the MAC address from ONT.
