# firewalld zone public (eno1)

## Current (2026-07-10, verified)

Expected open ports after Forgejo git-SSH:

```
sudo firewall-cmd --list-ports
# … 80/tcp 443/tcp 8080/tcp 9000/tcp 9001/tcp 23235/tcp 9200/tcp
```

| Port | Purpose | LAN probe (2026-07-10) |
|------|---------|------------------------|
| 80/tcp | `http-proxy` → Caddy 9000 (IPv6 HTTP/ACME) | via Caddy path |
| **443/tcp** | `https-proxy` → Caddy 9001 (IPv6 HTTPS) | via Caddy path |
| 9000/tcp | Caddy HTTP (WAN:80 → 9000) | **OK** |
| 9001/tcp | Caddy HTTPS (WAN:443 → 9001) | **OK** |
| 8080/tcp | Tor OR | — |
| 23235/tcp | (legacy list; host SSH is :22, WAN via VeciGate 23235→22) | — |
| **9200/tcp** | **Forgejo git-SSH** (podman rootlessport) | **OK** after add+reload |

### Not opened on purpose

| Port | Note |
|------|------|
| 9020–9024 | rootless apps; public HTTP only via Caddy → `127.0.0.1:90xx` |
| 9024 | Forgejo HTTP internal to Caddy only |

LAN `nc` to 9021/9024 → **connection refused** is expected without firewalld open (and not required).

### Commands

```bash
sudo firewall-cmd --permanent --add-port=9200/tcp
sudo firewall-cmd --reload   # or systemctl restart firewalld
sudo firewall-cmd --list-ports
```

### Verify (from another host on LAN / WAN)

```bash
nc -vz 192.168.100.95 9200
nc -vz 212.51.151.254 9200          # hairpin / public A
ssh -p 9200 -T git@git.hacktivism.ch
# expect: Hi there, … authenticated … Forgejo does not provide shell access.
```

### Why 443

IPv4 HTTPS is DNAT’d to **9001**. IPv6 has **no DNAT** — clients hit host **:443** directly.

### Why 9200

Forgejo advertises `SSH_PORT=9200`. Traffic hits **host:9200** (not Caddy). Without firewalld **9200/tcp**, clients get **connection refused** even while `ss` shows LISTEN and localhost works.

## History

| When | Change |
|------|--------|
| 2026-07-09 | 443/tcp re-added for IPv6 |
| 2026-07-10 | **9200/tcp** for Forgejo git-SSH (verified LAN + hairpin + SSH auth) |
