Hetzner 1 IP + Proxmox + OPNSense 和 NAT

Hetzner 1 IP + Proxmox + OPNSense 和 NAT

我在 Hetzner 有一台服务器,有 1 个公共 IP...

我在里面安装了 Proxmox,将所有流量引导到带有 OPNSense 的虚拟机。

这是我的 /etc/network/interfaces

source /etc/network/interfaces.d/*

car it
iface lo inet loopback

iface lo inet6 loopback

car enp4s0
iface enp4s0 inet static
         address 78.46.XX.76/27
         gateway 78.46.XX.65
         up route add -net 78.46.XX.64 netmask 255.255.255.224 gw 78.46.XX.65 dev enp4s0
         post-up iptables -t nat -A PREROUTING -i enp4s0 -p tcp -m multiport ! --dports 8022,8006 -j DNAT --to 10.10.10.1
         post-up iptables -t nat -A PREROUTING -i enp4s0 -p udp -j DNAT --to 10.10.10.1

# route 78.46.XX.64/27 via 78.46.XX.65

iface enp4s0 inet6 static
         address 2a01:4f8:121:4c9::2/64
         gateway fe80::1

car vmbr0

         address 10.10.10.0/31
         bridge ports none
         bridge-stp off
         bridge-fd 0
         post-up iptables -t nat -A POSTROUTING -s '10.10.10.1/31' -o enp4s0 -j MASQUERADE
         post-down iptables -t nat -D POSTROUTING -s '10.10.10.1/31' -o enp4s0 -j MASQUERADE

# OPNSense WAN - Proxmox LAN

car vmbr1
iface vmbr1 inet manual

         bridge-stp off
         bridge-fd 0
#LAN

在 Proxmox 中,我有一个带有 IP 192.168.1.1 的虚拟机,其中装有 OPNSense

在 192.168.1.100 我有一个 Web 控制面板(如 cpanel webserver/电子邮件等...)

如果我在 opnsense 中禁用了反射......

  Reflection for port forwards
  Reflection for 1:1
  Automatic outbound NAT for Reflection

我可以毫无问题地发送和接收电子邮件......但是虚拟机无法相互交互,这就是为什么我无法通过 cpanel 从虚拟机发送电子邮件的原因。

现在...如果我激活反射......

我可以在虚拟机之间进行交互...它们连接并将电子邮件标记为已发送...但服务器会自动退回我的电子邮件。

Nothing to worry.

但是...如果我从 Gmail 发送电子邮件到 cpanel 内的任何托盘...它们都会顺利到达!

有人可以帮帮我吗?
