subnet routing

General question: I have a /28 subnet and am planning (as i have not many servers and vms) to give each of my vms a subnet ip. I already got this working, to a point, where i had internet, but i had no firwall whatsoever. I already did this before and had a single IP with an OPNsense firewall...

Hello all, I have following virtual environment -> 3 isolated networks, each with own subnet and virtual router -> proxmox server has one NIC with one port -> on these networks will be vulnerable VMs to pentest I want my physical machine to be connected to these virtual networks... For...

hi, I cant access any other subnets from my pve node. i have a couple of vlans. at the moment my pve-node (pve) is in the management subnet (10.1.20.0/24 - vlan: 120) and the vms are all running in the service subnet (10.1.10.0/24 - vlan: 110). i can access the proxmox ui from any subnet...

I have a two-node PVE cluster currently hosted on my LAN at 192.168.1.*, but I would like move the webGUI management to it's own subnet at 192.168.100.*. I've gotten communication between my LAN and the subnet working and have confirmed this by deploying and pinging VMs on the subnet from my...

I look for support and guidance around where I am going wrong in a PROXMOX environment that I am setting up. I have one server that is connected and working for the Test Environment. It is running on the 172.16.0.15/16 network. We have three more servers that we have set up in cluster. The...

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...

Hi, I have installed proxmox on an OVH cloud, following a restart of the cluster I can no longer reach the VMs of one of my subnets. In practice I have a vm that has the wan in the subnet 192.168.3.x / 24 and from the cluster it is not reachable. below I am attaching the configurations set on...

Hello guys, I'm pretty new to Proxmox and virtualization/networking in general and I've searched for this topic quite a bit. So basically my problem is that I have a dedicated server on Hetzner with the IP (65.21.121.xxx) and I got a subnet package from them for me to assign an...

Hello all together, i got a Rootserver and an /29 Subnet from Hetzner. First of all we setup the Server with Proxmox without any problems. But i got a couple of strange problems setting up the network-bridges and a "real" VM and i really don't get the problem. Firewall is disabled. Not being...

Hi folks, a found a nice article in Hetzner's Wiki which describes how to use all (!) IP addresses of a given subnet for KVM VMs. I.e. not (x - 3) subnet addresses because no need of dedicated addresses for bc, gw (vmbrX) and net. What do you think of this solution described on Hetzner's...
