Kerala Vision Broadband FTTH - User Experience

Now that I am evaluating Kerala Vision broadband, thought I would create a thread to share my experience. My LCO provides broadband services from BSNL and Kerala Vision, so thought would be good to evaluate Kerala Vision as well.

Getting the account setup was pretty easy, cause there was no need for additional cabling or ONT etc. I shared a photo and ID/address proof doc to the LCO, and the same day evening he setup my account and shared the credentials. The LCO shares the same OLT for all services, so on my end, I just needed to configure my OpenWRT device appropriately.

Initially I didn't get the Kerala Vision VLAN, so I had to reach out to the LCO's tech guy who shared the id. I added the VLAN to the switch (my ONT is a transparent bridge, so I needed no change on the ONT) which created an interface and all I needed to do was add the necessary interface configuration with the PPPoE credentials.

As you can see, they use CG-NAT which is disappointing but other than BSNL and few others nobody else gives public IP addresses. Also I liked the fact that things just worked on first try (the above screenshot is from my first try to connect)

Will add more details as I explore more.

okay , cool.. One thing i noticed is that when I try to scan the WAN IP , it says the SIP port is closed :

pi@raspberrypi:~ $ nmap -Pn 117.201.6.219

@varkey what could be the issue ? some routing issue at BSNL or I my configuration is wrong ?

 

[varkey]

Wrong config, my guess is that the IP address is wrong.

You cannot ping that IP address from the internet interface. It is accessible only from the voice interface.

I have routes configured separately so it works, but the same may not work for you.

Please elaborate the details for us noobs, this got me curious

 

[varkey]

Nothing special, just two static routes which says any traffic to the voice subnets should go via the voice interface.

thanks @varkey for your help. Not sure what happened in between , voice is working fine since this morning Incoming , outgoing all working fine.

Btw , how can I see the usage etc , is there any portal available ?
