nat

I have multiple LXC containers which use a nat configuration. I'd like to implement fail2ban on them but since the main firewall is placed on the Proxmox itself I don't know what's the correct way to use fail2ban on containers. I mean, by default, fail2ban actions try to add rules on the local...

Hi! I went ahead and set up PVE on a remote server and then used the instructions here to set up NAT so that the VMs can access the internet. This works just fine. However, my end goal here is to be able to access these VMs directly via the Internet as well. Let's take SSH access as an...

Hello everyone, I'm trying to build a Proxmox-Host with LXC-Containers in the HETZNER Cloud. Basic information about the current network: Home network <-> pfSense (onprem) <-> pfSense (in HETZNER Cloud) <-> PVE host <-> LXC-Containers Home network: 10.0.0.0/16 Cloud network: 10.10.0.0/16...

I am experiencing an issue with my Nginx setup on Proxmox. All services work fine for the external network—if I try to visit abc.mydomain.com, which is pointed to my Proxmox server, it works as expected. However, when I try to access the site from the internal network, it does not work. I am...

Hi, I have an issue with network configuration on my Proxmox server. I really want to have remote access to the configuration panel, the NAS server, Homebridge and VM hosted on the server. The problem is my Internet provider, who won't provide me with a public IP address. I don't have a static...

Dear all, EDIT: RESOLVED FINALLY !!! I changed the 'vmbr0' to 'eno1' in the NAT configuration. Worked after rebooting the node. Now VM has internet access. I have a requirement to setup multiple VMs in different isolated networks. Also, these VMs should be able to have internet access. So...
