masquerade

Hello, I really need help to understand what is the best network configuration I shall make. I have 3 Public IPs that share the same /24 netmask, thus they have the same gateway. At first, I tried using only one of them and route all my VMs traffic through it using Masquerading (my VMs have to...

I'm pretty new to Proxmox (I've successfully set it up before but not using masquerading). I'm trying to set the network up so that all of the traffic is routed from the Proxmox IP to one of the VMs which is running HAProxy, so that it can send that traffic onto whatever backend should handle...

Summary: Having trouble mixing public and private IPs on a PVE host. Help! Details: I have a PVE host with a public IP and an additional /28 block (not contiguous with with host's IP). Everything works fine and all provisioned VMs have public IPs, which is appropriate for their use cases. The...

What I'd like to do: Migrate away from a host with about 15 public IPs to a single public IP with all VMs getting static or DHCP addresses in the 10.10.10.x space. Many of these VMs serve up multiple services -- for example, a dozen WordPress sites on a single Webinoly or WordOps VM. Where...

Requests from VM in subnet are forwarded to pve's gateway, but with subnet source IP. My masquerading with iptables fails in this common use-case: Internet <-eth0-> pve host <-vmbr0-> VM (10.10.0.1) With sudo tcpdump -n -i enp0s31f6 icmp I get: 17:26:35.506557 IP 10.0.0.2 > 94.130.yy.zz: ICMP...

https://pve.proxmox.com/wiki/Network_Configuration#sysadmin_network_masquerading I'm currently using this setup because my hosting provider gives me a single IPv4 address, so I have to set up masquerading. I'm setting up a new Proxmox host, and I'm considering adding IPv6 configuration from...

I'm new to proxmox, Is there anyway I can directly access VMs without iptables NAT entry? For example I wish to ssh with port 22 to 2 different VMs inside my proxmox, current setup is port 41 for 1st VM and port 42 for 2nd VM. num target prot opt source destination 1 DNAT...

Hi, I've a network problem on Proxmox configuration. I've installed Proxmox on a Cloud VPS (provider uses VmWare VE) with only one NIC and 3 public Ip addressess (same subnet and gateway). My goal is to assign one public Ip to the Host (Proxmox VE) and others to VMs I tried to configure a...

I've got a server from leaseweb with PVE 7 on it, attached to the public facing ip I'm using the PVE firewall to manage incoming connections, and the masquerading nat to provide a NAT for my containers and vms As an LXC guest I'm running PBS 2, but I can't seem to get it to accept on port...

Hello, I can´t figure out how to get this done. What i have: I have one public IP on a Rootserver connected to PVE via ens3 bridged to vmbr0 where Gateway and IP are set. I also created a new network to masquerade vmbr0 to vmbr1 for connection between Containers on Subnet 10.10.10.1/24 auto...

I'm trying to set up Proxmox in a way that all VMs would use the same interface with manual port forwarding. I found this post that pretty much describes what I want to achieve: https://forum.proxmox.com/threads/how-to-config-same-ip-for-all-vm.34748/post-170333 But sadly it's rather...

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...

Hello! Let me try to explain what I am trying to do. On the proxmox server, I will have 4 VMs (centOS 7): a load balancer / reverse proxy 2 web servers 1 database servers The load balancer will have a public IP but the 3 other ones will have a private IP. On the host, I do have the...

Hi everyone; When I activate the firewall at the cluster level 1. I have to open port 22 and 8006 unless I loose connection; (which apparently not suppose to happen) 2. my container are unable to communicate with the world. but as soon I disable the firewall everything is fine. - I is Proxmox...

Hi. I have instaro proxmox version 5-2-8 updated everything works OK, my server has 4 network interfaces one for the wan, another for an external network with optical fiber and two for the lan, reading I saw that I can make a virtual private network and with the method Masquerading (NAT) with...

Hello, I have Dedicated Server on Hetzner with a single NIC and a single public IP on it. There are quite a few discussions about setting up Proxmox networking in such a situation. Specifically, I have followed the following guides: forum <dot> proxmox <dot>...

At first I had Proxmox working using the interface enp2s0f0 and bridge vmbr0 which is connected to a DHCP private network. I wanted one VM to be reachable from WAN though so I added enp2s0f1 and masqueraded vmbr1 which is connected to a static public IP address. Everything works but once I...

Hi, I have been struggling to get NAT working for a container with only partial success : it works when I run the command from a shell but does not work when I set it up in /etc/network/interfaces. The host runs debian 8 and proxmox 4.4.12 (upgraded from v3, itself upgraded from v2). So, as...

Proxmox 4.4 with CentOS 7 guest in container. Host can reach the internet, but containers cannot. It seems others have had similar problems but I cannot find a solution. Host /etc/network/interfaces auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.0.2...

Hello. I'm running Proxmox 4.4-1. I followed the guide at https://pve.proxmox.com/wiki/Network_Model for setting up Masqueraded NAT since my Proxmox host has a single public IP (example as 10.0.0.174 below), but my containers can't reach the Internet. They can ping my Proxmox host's gateway...
