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?
