# Synology Snapshot Admin Firewall and Reverse Proxy Copy-Paste

Use these values verbatim in DSM.

## Reverse proxy

- Rule name: `snapshot-admin`
- Source protocol: `HTTPS`
- Source hostname: `admin.example.com`
- Source port: `443`
- Source path: `/`
- Destination protocol: `HTTP`
- Destination hostname: `127.0.0.1`
- Destination port: `8787`

## Firewall

- Allow: `443/TCP` from WAN or trusted CIDR
- Deny: `8787/TCP` from WAN
- Optional allow: `443/TCP` from office/VPN CIDR only

## Certificate binding

- Hostname: `admin.example.com`
- Bind to: reverse proxy rule `snapshot-admin`

## Notes

- Do not expose `8787/TCP` directly.
- Keep Basic Auth enabled in the Python service.
- Use `127.0.0.1` for the destination host unless direct-bind testing is intentional.
