Remote access comparison
Dynamic DNS vs Public Tunnel
Both help people reach self-hosted services, but they solve different network problems.
Dynamic DNS
Best when your service is already reachable from the internet and only the public IP changes.
- Works with router port forwarding.
- Keeps a hostname pointed at the current IP.
- Ideal for normal dynamic-IP connections.
Public Tunnel
Best when inbound access is blocked or you cannot change the router.
- Uses an outbound-only connection.
- Good for local web apps and dashboards.
- Works even when port forwarding is unavailable.
Quick comparison
| Question | Dynamic DNS | Public Tunnel |
|---|---|---|
| Need public inbound access? | Yes | No |
| Need router changes? | Usually yes | No |
| Best first use | Changing public IP | Web access without port forwarding |
| Good behind CGNAT? | No | Often yes for web access |
How to choose
If your router can accept inbound traffic, start with Dynamic DNS. If the router cannot be changed, inbound access is blocked, or you are behind CGNAT, look at Public Tunnel or Static-IP Relay instead.
