Bridged Network Adapter Does Not Connect Outside Server Environment

[Chris Welber]

I have a Proxmox VM that is setup with a bridged node network adapter, but it's not able to receive a DHCP IP from the DHCP which is on the same subnet as the Proxmox host. If I assign a manual IP to the VM in the subnet the Proxmox host is in, it can ping the Proxmox host but nothing outside of the Proxmox host that is in the same subnet.

Is this a setting I need to make on the VM or Proxmox host?

Thanks,

Hi,

this sounds like the network is not setup proper.
Can you sent the network config.
/etc/network/interfaces

(Sorry I created double threads, so feel free to consolidate them).

Here you go, I added the "eth1" interface in the GUI, but only NAT worked prior to that as well. My goal is to get bridging working from VM's where I manually assign a static IP outside the host system. If possible I would like to have the Proxmox host bridge eth1 too:

root@pve:~# cat /etc/network/interfaces
# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
#
# If you want to manage part of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!
