I have found an special offer 1$/month for a VPS with only IPv6 addres / 512MB RAM / 500GB bandwitdh at 100Mbps and after that unlimited but the speed is limited to 5Mbps so i said it’s the perfect candidate for a Snowflake bridge.

Somehow it seems that NAT type is unknown.  
Is something that i can do to force the bridge to work in IPv6 mode only or what can be the issue of not getting users? 😃

@SirNeo did you find a solution for this? My IPv6 prefix is dynamic, and I would like to use it to run a Snowflake standalone.

I’m afraid that the issue is that as of writing the Snowflake broker makes no difference between IPv4 and IPv6-only proxies, so it may hand IPv6-only proxies to IPv4-only clients. IPv6 is not widely supported, thus most connections would fail.  
I am not sure then if it’s beneficial to run such a proxy. On one hand some connection succeed, so the proxy does contribute to the IP address pool. On the other hand this slows down the bootstrap for most clients.
