ZeroTier + Proxmox We have been using ZeroTier over a year, when it came time to use it with Proxmox, I wasted hours due to my desire to over-complicate things. This four step process will let you access your containers and VMs remotely via the ZeroTier D-WAN / VPN My goal is to configure...

Hi and thanks for your help. I have no networking for my first VM in my new Proxmox 6.2 installation.....here is my /etc/network/interfaces : auto lo iface lo inet loopback iface enp8s0 inet manual auto vmbr0 iface vmbr0 inet static address 88.198.26.141/27 gateway...

I wrote this to redirect all ports to a single machine, but I don't know if it is working properly. Is it possible to direct the entire port range to a single machine like DMZ Logic? post-up iptables -t nat -A PREROUTING -p tcp --dport 0:8005 -j DNAT --to-destination 192.168.128.185:0-8005...

I had been trying to create a private IP (NAT) setup for my VMs and managed to do it as follows, heavily relying on infomation in reference [1]. I have re-titled this as a Tutorial now: 1. In the Proxmox web interface for the host network configuration create a second bridge: vmbr1 with IP...

Hi guys, I got another problem today. I got a proxmox node (running version 6.1-8) that has got one public IP (lets say A.A.A.A) and one secondary IP (lets say B.B.B.B). I also got a bridge with the internal network 192.16.8.0/24 where every VM gets an IP. Currently my setup is working and I...

Hi, I have a proxmox setup with one public IP, that's why I have a NAT network with port forwarding. Everything works fine from outside the NAT network, except when I try to reach a server inside the NAT network from any other server inside the NAT network. I already configured the loopback...

Guten Tag, ich habe ein (hoffentlich) kleines Problem. Ich habe für meine freigegebenen Ports nun Einträge in der Firewall auf dem (Rechenzentrum) angelegt und die Firewall dort und in der VM an sich aktiviert. Jetzt möchte ich zum Beispiel den in der interfaces gerouteten Port 1222 (zur...

Hi, I'm trying to setup some containers using a standard NAT config. Unfortunately, I can't get the containers to access to outside their LAN. The Proxmox host is behind a router (192.168.1.254). It has a perfect Internet connectivity, and can ping the container with problem. At this moment...

Hello, I have installed Wireguard in Proxmox KVM virtual Ubuntu Machine, because many changes must be do for running it into a lxc container. My Wireguard works fine clients can connect and everything worked. So my Wireguard VM have a network adapter with a public ip address. So I enabled the...

Hello, for some test scenarios i need to isolate a copy of VM from the network itself but still need to be access it via dedicated ports. Example. Proxmox host: 192.168.0.10/24 I have a VM0 (bridged) with IP 192.168.0.1 in a LAN with network 192.168.0.0/24 and LAN gateway 192.168.0.254. Now i...

I am running proxmox on a local server. All my VMs are of the 10.0.1.0/24 subnet. How do I NAT my VMs to allow access from the outside world? Where can I find a reliable guide for doing this? I have never done any NAT before.

Hello, im playing around with Proxmox at home wanting to put it on a dedicated sever at Hetzner later, and have some trouble using a private network for the VMs. The config below works, i can Ping from a Container in the private net(192.168) to my Desktop in my LAN (10.10), and if i look at...

Hi all! me again. I've been working for around 1 week trying to use Proxmox over ESXi but this is giving me way too many headaches. Still, I think this time the issue is not Proxmox, but my lack of networking knowledge. Anyways, this is what I'd like to archieve: Basically, my server...

Hello all, First time poster here, I've been following Proxmox for a while and now I've set up a VPS in an external provider. My current provider gives me a Supermicro server with only 1 NIC plugged in. I have no control over this as I've already made a ticket to ask my provider to plug another...

I continue with the topic of networks. I have a practical case, this time is to create a network (for a hypothetical company) and divide it into several subnets. The most normal thing would be to divide it with the mask but if one computer changes the mask the others will be seen. So it...

Hello, I can't figure it out by myself even after searching google for many hours. The VM can access Web as soon as I deactivate Proxmox VM Firewall for this specific VM Windows Server 2016. It makes no sense for me because setting is outgoing policy "accept" I can reach the VM over Internet...

I'd like to enable port forwarding for IPv6. For IPv4 I just simply appended this at my /etc/network/interfaces: post-up echo 1 > /proc/sys/net/ipv4/ip_forward I tried to append this for IPv6: post-up echo 1 > /proc/sys/net/ipv6/conf/all/forwarding but, once rebooted, system says "connect...

(Please see attached image) I have a single host with four interfaces (2x 1Gb, 2x 10Gb). eno0 is used for the external nat/route to the upstream firewall and external access via 172.16.27.1. eno1 is not currently used, but *will* be used as a 1Gb guest bridge into a switch (10.0.30.x)...

Hi, I have setup containers with NAT with the following network configuration: For each container, I add bridge vmbr2 and assign an IP address from 10.1.1./24. For internet access, the container uses NAT/MASQUERADE and goes through vmbr0, which is the public facing interface. To redirect...

Hello, is there any way to configure DNAT, and SNAT to hosts via pve-firewall? Currently we use for outgoing connections: iptables -t nat -A POSTROUTING -s 192.168.64.0/24 -o vmbr0 -j SNAT --to-source 5.7.9.99 iptables -t nat -A POSTROUTING -s 192.168.80.102/32 -o vmbr0 -j SNAT --to-source...
