I am thinking of trying BSNL brodband. I want to connect to home network that has my nas and media server over the internet (natively, without tailscale). I tried Catla Brodband, who give natted ipv4 and no ipv6. Currently have airtel brodband that have a fully lockdown router and cant even enable bridge mode. So thinking of good old Bsnl. I tried registering in app but no response even after 4 months. So if any one have LCO's number please share. Also if any one have any better suggestions, please do tell.
