Private Network with NAT for VMs on Proxmox with Single Public IPv4

admin1 Comment

I have a dedicated server with only 1 Public IPv4, without a router in front to manage the network. So I should use the power of iptables and proxmox to create a private network for the VMs. Virtual machines will communicate with the world through NAT. Long story short:
Internet <-> vmbr0 (default bridge with static IP) <-> vmbr2(second bridge, that I will create) <-> Virtual Machines

Proxmox Firewall, which is just iptables, will take care of network security.
Port forwarding? no worries, iptables will take care too.

Dedicated server from OneProvider – first impressions

It is time to replace my old boy – Fujitsu rx300 s6.
It worked for 3 years in my basement, with regular loss of electricity, a lot of dust and no air conditioner – what a champ. Unfortunately, there is no place for my noisy fella anymore. I was thinking of placing it in some data center, but the prices are too high – 300 euros per month for a server with 2 power supplies ~ 2000W and one public IPv4 (100mbps). It was used only for personal, small projects and testing purposes. So I need something cheap to rent, with:

  • 12 CPU threads
  • 32 GB of RAM
  • Gigabit internet connection
  • Data Center must be in Europe
