Good Morning everybody; this forum seems to be having a lot of information on networking in India. Great place for knowledge sharing and thank you members for making this forum such a wonderful & useful place.

We have an FTTH connection from BSNL and they have placed an Alphion AONT-100C modem. Since this modem doesn't have wifi feature, we have added a TP-Link router and connected many computers through wifi. Everything was fine until now when we want to use one of the computer in the network as a web server which has to be made accessible from public. Looked out for many tutorials online and tried our best with no success. So, please help with our situation.

EXISTING SETUP:
Modem: Alphion AONT-100C
LAN IP: 192.168.1.251
WAN IP: Dynamic
Connection Type: PPPoE
DHCP: Enabled

Router: TP-Link
LAN IP: 192.168.0.1
WAN IP: 192.168.1.127 (Dynamic)
Connection type: Wireless router
Connection in: LAN cable through WAN port from AONT modem
Connection out: Wifi and LAN ports

Web server machine: HP Workstation
LAN IP: 192.168.0.105
Listening to port: 80
Allow access: all

We tried two methods:
METHOD-1
Enabled DMZ (firewall settings) in BSNL modem with host 192.168.0.1 (TP-Link router) and port forwarded to 192.168.0.105 in the TP-Link router. Incoming public traffic is routed to BSNL modem admin page.

METHOD-2
Made the TP-Link router as an Access Point with IP 192.168.1.1 and assigned web server machine with IP 192.168.1.105, both having gateway as 192.168.1.251 which is the BSNL modem. Enabled port forwarding in BSNL modem to point to 192.168.1.105 (80 port). Incoming traffic is still routed to BSNL modem admin page.

We also tried with some different ports instead of 80, which didn't work either. Please help.
 
I replied to your other thread on this bridge mode problem.

You don't need to clone MAC of the ONT. BSNL binds MAC for the ONT itself, not for PPPoE. I confirmed this with BSNL itself a long time ago when I got my connection. I use fake MACs for my PPPoE connection. Makes it more private and secure.

Not in every city/state, it varies. Southern states it appear to be MAC bound.

@newbie2902 Looks like it's not possible. That crap ONT from BSNL does not even have modern-day feature set. I think it's time you bought your own ONT. But you will need to inform BSNL first because they'll need to update the MAC on their end.

^ Not necessarily everywhere again, I was able to swap my ONT without any BSNL or LCO involvement. Again, if it's through an LCO, it's the LCO who manages the ONT auth parameters and config, so if they have an ONT whitelist you'd need to contact the LCO.

When they installed the new connection at our place, the LCO configured everything but the authentication failed. Then he called the BSNL office and they whitelited the MAC after which PPPoE authentication was successful.

Will check with the BSNL office if we can have our own ONT device and they will have its MAC whitelisted.

Meanwhile, will also try @Manoj Mathew suggestion on DMZ & port forwarding.

Thank you very much @Dark_Nate for your time in helping on bridge mode.

Bottom line conclusion is that IT IS NOT POSSIBLE TO SET BSNL Alphion AONT-100C MODEM ON BRIDGE MODE.
