Networking NAT e vSwitch - Proxmox Hetzner
Configuracao de rede NAT single-IP e vSwitch para Proxmox em Hetzner.
Networking NAT (Single-IP Hetzner)
Configurar /etc/network/interfaces
Template para Single-IP NAT:
auto lo
iface lo inet loopback
# Interface fisica (verificar nome com 'ip a')
auto eno1
iface eno1 inet static
address SERVER_IP/32
gateway GATEWAY_IP
pointopoint GATEWAY_IP
# Bridge interna para VMs (NAT)
auto vmbr0
iface vmbr0 inet static
address 10.10.10.1/24
bridge-ports none
bridge-stp off
bridge-fd 0
# NAT masquerading
post-up echo 1 > /proc/sys/net/ipv4/ip_forward
post-up iptables -t nat -A POSTROUTING -s '10.10.10.0/24' -o eno1 -j MASQUERADE
post-down iptables -t nat -D POSTROUTING -s '10.10.10.0/24' -o eno1 -j MASQUERADE
CRITICAL Hetzner Gotchas:
- Gateway /32 point-to-point (nao /24 ou /26)
- IP e gateway podem estar em subnets diferentes
- Verificar IP real e gateway no Hetzner Robot
Aplicar Networking
# Test config
ifup --no-act vmbr0
# Apply
systemctl restart networking
# Verificar
ip a
ping -c 3 8.8.8.8
Port Forwarding (Opcional - para expor VMs)
# Exemplo: Redirecionar porta 8080 host -> porta 80 VM 10.10.10.100
iptables -t nat -A PREROUTING -i eno1 -p tcp --dport 8080 -j DNAT --to 10.10.10.100:80
# Persistir com iptables-persistent
apt install iptables-persistent
iptables-save > /etc/iptables/rules.v4
vSwitch Configuration
Configurar VLAN no Robot Panel
- Hetzner Robot -> vSwitch -> Create VLAN
- Anotar VLAN ID (ex: 4000)
Adicionar ao /etc/network/interfaces
# vSwitch interface (MTU 1400 OBRIGATORIO)
auto enp7s0.4000
iface enp7s0.4000 inet manual
mtu 1400
# Bridge vSwitch
auto vmbr1
iface vmbr1 inet static
address 10.0.0.1/24
bridge-ports enp7s0.4000
bridge-stp off
bridge-fd 0
mtu 1400
CRITICAL: MTU 1400 nao negociavel para vSwitch Hetzner.
Hetzner-Specific Gotchas (CRITICAL)
1. MAC Filtering
Problema: Bridged networking com MAC nao registado = bloqueado Solucao aplicada: NAT masquerading (bypass MAC filtering) Alternativa: Pedir virtual MAC no Robot panel (gratis)
2. Gateway Point-to-Point
Problema: Gateway fora da subnet do IP principal
Solucao: address IP/32 + pointopoint GATEWAY (nao /24 ou /26)
3. vSwitch MTU 1400
Problema: vSwitch Hetzner requer MTU 1400 (nao 1500 standard)
Solucao: Forcar mtu 1400 em vmbr1 e enp7s0.4000
4. ZFS vs LVM Trade-off
Problema: installimage nao suporta ZFS root directo Solucao: LVM para root (compatibilidade), ZFS para VMs (performance)
5. Kernel PVE vs Debian
Problema: Kernel stock Debian nao optimizado para virtualizacao Solucao: Instalar proxmox-ve + remover kernel Debian
