| Free tier | Static routed /64 per tunnel, up to 5 tunnels per account, 100 Mbit/s per tunnel, dynamic IPv4 endpoint updates (dyndns2), self-service reverse DNS (PTR) - 0 kr / forever unit unlimited; metered on none |

| Price | USD 0 |

| Limits | - per-ip-shaping 100 Mbit/s per tunnel source
|
|---|
| Binding | none 100 Mbit/s is about thirty times the 3.24 Mbit/s that 1 TiB/month needs, and no byte quota is published, so nothing in the vocabulary fails at that volume. The real gate is protocol 41 reachability plus a public IPv4, and reachability is IPv6-only for the reader. |
|---|
| Identity | email 'Create an account at free.tunnel64.net and tell us the public IPv4 you connect from.' The paid VPN advertises 'Email-only signup - no name, no phone'; the free tunnel page states no field list. |
|---|
| Egress | no traffic allowance is stated for the free tunnel; 'Unlimited traffic' is listed on the paid VPN plan, not on the free tunnel plan; ingress: tcp+udp free allowance: none published |
|---|
| Interface | cli 'Copy the generated config - plain Linux, OpenWrt, or Windows. Standard 6in4, no client software' |
|---|
| Tooling | four ip commands on Linux or a pasted router config; ddclient for the dyndns2 endpoint |
|---|
| Composes with | needs a host with its own public IPv4, so it fits a free VM with an IPv4 address rather than one behind NAT. |
|---|
| Reliability | 'Outbound port 25 is blocked by default' on the VPN side; the free tunnel plan publishes no SLA. |
|---|
| Notes | Run on AS35100 from Sweden and the Philippines. A routed /48 tier is announced but not on sale. The free tier has no WireGuard, so a client that cannot receive protocol 41 gets nothing here; the paid VPN is the WireGuard path and it is priced, not free. |
|---|
| Evidence note | documented documented from the vendor page read. No WireGuard on the free tier is the fact most worth re-checking, because the provider sells a WireGuard VPN next door. |
