• The Right Way to Use WebArena Indigo

  Wednesday, June 17, 2026Made with AI

  WebArena Indigo is a cheap, good-value Japanese VPS that makes a great landing node. But if you front it with a relay and push traffic over a GRE tunnel like I did, GRE over IPv4 gets rate-limited the moment you run a speed test — the connection collapses right after the first burst. This post walks through what I tried (realm public forwarding, IPv4 GRE, IPv6 GRE) and how I ruled out snell, MTU, DNS and the qdisc one by one, landing on the conclusion that only GRE over IPv6 (ip6gre) reliably escapes the rate limiting. Plus a note on picking between the 500M/4-core and 1000M/6-core shared plans.
