bridge

Hi all, running into issues where the VMs will lose access/no longer able to connect after toggling connection, rebooting, etc. The VMs are able to receive an IP (static and leased) and I'm able to ping them from other devices (vice-versa), but I am not able to reach the internet. Any...

I've tried asking on ServerFault (https://serverfault.com/questions/1134269/where-to-put-vlan-interface) because it's not strictly a proxmox question. But I received no answers, only a suggestion to post on this forum, so I'm reposting here. I have 2 x 1 Gbps network interfaces. On top of them...

We have an overlay network (configured as described below) which worked fine on PVE6.4 but after migrating the containers to a PVE 7.2 node have noticed some odd behavior, with packets above a certain size being discarded by the vxlan interface, but only when sent from a container, VMs continue...

I use a little NUC with an integrated Wifi-module as a proxmox-host. On the proxmox-host runs a "home assistant"-VM. Because a "shelly EM"-sensor is too far from my Wlan-router, i placed my NUC nearer to the shelly EM, to have a better Wifi-connection from my NUC to the sensor. The NUC is...

Hi, I'm going to implement a trunk and some access ports on proxmox to the Cisco Switch in my homelab. Probably adding a bond or two but let's keep it to simple bridges for now. I'm studying the docs and different guides on how to implement vlan trunks and vlan tagging, and I see mostly two...

Hi According to the documentation, Proxmox uses tap devices (layer-2 devices which accept Ethernet frames) along the virtual switch (Vmbr0). I am not understanding why vmbr0 has an IP address, what is it needed for? and what is it used for? The code below is taken from the documentation for the...

Please bear with me I am very new to proxmox and linux in general. I installed proxmox a couple of months ago, created some vms and lxc and everything is going great. By default proxmox created a Linux bridge (vmbr0) using the network card on my motherboard enp7s0. After reading about pfSense I...

Hello. I'm trying to configure my proxmox setup in a way that my main ipv4 is used by the host itself (the routed configuration in here), while the secondary ipv4 is used by the pfSense VM and then propagated by that to other VMs. Based on Hetzner documentations I have changed my...

I wanna give access to a Linux VM to a friend of mine, but I don't want him to be able to see the other devices on my network. Is there a way I can set it on a separate network so that when it connects, it looks to to him like the VM and the "router" are the only 2 devices? Thank you

Hello! In a VM I created a network namespace "ns_twsgw" (IP a.b.c.82, main IP a.b.c.81) with a bridged macvlan (second MAC address on the virtual ETH IF). I see all the ping packets from the "ns_twsgw" network inside the VM with tcpdump, but I don't see them on the bridge IF (e.g.: fwpr106p0)...

Hello all, I am trying to set up OPNSense on my Proxmox server and disallow Proxmox from accessing the internet directly, as it's plugged directly into the modem. I am still learning - excuse me if this is a simple request Expectations...
