nat

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...

Hello So i installed Proxmox on my server. I configured a Bridge and NAT interface for my VM's. I installed my first VM (Ubuntu) configured the port forwarding and tried to connect to it with putty -> Connection time out. I double checked everything twice, firewall, ip configs, ports, but i...

Hi all! I've been since a couple of days trying to configure NAT in my Proxmox VE. I've followed some steps here and other tutorials on the internet but I couldn't get it work. I can ping my VM from my PVE succesfuly but I don't have connection from my VM to the PVE or to the internet. Here is...

I've googled for a few hours now on this but so far the answer eludes me. I'd like to set up a coupler of LXC containers (not VMs) which are situated on their own LAN ie 192.168.1.0. They can see each other and they can both access the outside world through one NATted WAN IP address. I'd then...

Since NAT option was removed in VE 5.2 can anyone help on how to simulate the scenario using OVS!

We are a data center with 6 nodes of Proxmox VE and growing. We have customers that come to our website and order their VPS through our WHMCS which is using Proxmox VPS/Cloud module. We already have Cisco ASA Firewall which is handling our NATing and Vlans and everything is going smooth, but we...

I have server with proxmox and 2 public IPs. All VMs are behind NAT now and it works. But for new VM I need to assign public IP. I tried to create second bridge with second public IP and I have access to proxmox server via this IP. Then I tried to create VM and assign interface to new bridge...

For some reason the NAT config has been removed from the Web interface and is only available in CLI or the API ("This mode is only available via CLI or the API, but not via the WebUI."). In my opinion this is a very bad decision, because I (and I think allot of other people too) use this...

I think that it is too cumbersome to edit the network card file every time you add the nat rule. Can you add the iptables nat rule of the web interface in future versions to manage or provide the network card file modification channel or other means to simplify the nat port rule configuration...

Hi, I always worked around this problem, but now I'm just tired of it and want to do it right. My containers have IP and internet connection like this: https://pve.proxmox.com/wiki/Network_Model#Masquerading_.28NAT.29_with_iptables Lets say 10.10.10.100 is a mail server, and 10.10.10.200 is a...
