Easy steps to bridge your own
router, here's how I bridged the Airtel (ZTE F670LV9.0
ONT) with my AX20 router:
1. First speak to the local/installation team and If they're not aware, explain to them that it has to be enabled by the backend team on any/all of the ports of the airtel supplied router. I am not advising to directly raise a service request to cc as it gets raised as a service complaint to the local team. If the local team understands and agrees to get it done from the backend, jump to step 3.
2. If the local team is unaware and nothing works out, send an email to
121@airtel.com mentioning your account id/telephone number and it gets raised as a service request. This is mostly resolved within 1 working day.
3. After it gets enabled from the backend, either the local guy or cc will respond that Port no. 'X' has been made open to be used for bridging.
4. Don't change any of the settings in the ZTE. It should have by default two settings under WAN already enabled - VOIP and INTERNET.
5. No need to disable NAT on the ZTE.
6. In my case my Port 4 was enabled, inserted an ethernet cable to the WAN port of my router and the other end to the LAN port 4 of the ZTE.
7. Do a factory reset of your own router/ start Quick setup from the menu.
8. Choose the Internet connection settings type to PPPoE. Enter the supplied username as '<landlineno>
_dsl@airtelbroadband.in', your account number as the password and click connect. This will get connected to the internet.
9. Switch off the Wireless radio 2.4 and 5g in the ZTE under the Local Network.
10. Test for double NAT - open command prompt/terminal, enter
(
mac) or
(
windows). Check If the first two IP addresses are starting with 192.168... or not. If it does, then double NAT is happening, hence try checking the NAT settings. In my case, there was only 1 such IP address.
11. You're done.
As a few additional tweaks, disable DHCP on ZTE, enable IPV6 on your own router, etc.
Hope this helps.
