masquerade

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...

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...

Hello, I installed Proxmox 4.2 via ISO at my Server. Considering the fact that I only have one public IP address I tried to use NAT. This is my interface configuration: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address a.b.c.d netmask 255.255.255.224...

Hi Guys, Wondered if you could help me please... I have NAT (Masquerade) setup and working on my Proxmox setup. I also have the firewall enabled at the Datacenter, Host and VM levels. The Datacenter and Host level firewalls seem to be working perfectly and only allowing ports I have allowed...
