Self hosted open source mesh VPN with IPv6 support!

Anurag Bhatia
A rather long title but the post is about self-hosted open-source mesh VPN with IPv6 support and works with nodes behind CGNAT! This will be a long post documenting the concept of mesh VPN, the problem it is solving as well as a working demo. If you are not planning to deploy it right away, you can skip the post after the “Configs and setup” section. Problem I am running a site-to-site VPN for a long time between various servers located far away from each other.

Jio 5G - IPv6 only on transport

Anurag Bhatia
Last month I got access to Jio 5G like everyone else around in Haryana. They are running a beta program with uncapped data for now. Overall it works fine for usual stuff (web surfing on popular sites, YouTube videos, music streaming etc) but 464XLAT seems to be a little buggy in IPv4 hardcoded destinations. Initially it was giving quite a few issues but many of them seem to be fixed in last few days.

Why object storage is getting exciting?

Anurag Bhatia
Last year had many interesting developments and one of that has been object storage. For those unaware, object storage is de-facto cloud storage which stores data as objects instead of file system architecture. This gives the option of simple plug-and-play horizontal scalability. It became popular when Amazon Web Services (AWS) launched S3. The idea was straightforward - pay-as-go storage with a few cents/GB/month charge to store data and a few cents/GB to egress data.

Mapping major CDNs across Indian networks

I was recently discussing with a friend Jio’s Fifa streaming issues. Considering PNI capacity challenges with other telcos, I wonder if they were serving FIFA streams out of their network or if it would be on some CDN like Akamai. As I was testing, I noticed a couple of megs of flow data with my provider’s local IP. Turns out that was a local Google GGC node in Rohtak and as I try to connect to it, it replies on HTTP port 80 and 443.

OTT and paid peering

Anurag Bhatia
Yesterday there was an article in the Indian paper Financial Express with the title “OTTs may have to pay access charge to telcos”. Quoting a few points from the article: Social media intermediaries like WhatsApp, Facebook and Twitter, and over-the-top (OTT) players like Netflix, Prime Video and Disney+Hotstar may have to pay a carriage charge to telecom service providers Data, particularly video, comprises 70% of the overall traffic flow on telecom networks, and this would grow further with the rollout of 5G services Upon reference from the DoT, Trai is currently studying various possible models under which OTTs can be brought within the purview of some form of regulation According to sources, an interconnect regime is a must between OTTs and telcos because as 5G services grow, there would be immense data/ video load on networks, which may lead to them getting clogged or even crashing at times.
