Proxmox Network Configuration#

What Was Established#

Procedures for manually updating the IP address and network interface settings on a Proxmox VE host via the command line.

Key Decisions#

Network configuration is managed via the /etc/network/interfaces file. When changing network parameters, the Linux bridge (vmbr0) must be updated to point to the correct physical interface.

Current Configuration#

To modify the IP, gateway, or interface, edit the configuration file:

nano /etc/network/interfaces

Example of a static configuration for a bridge interface:

auto vmbr0
iface vmbr0 inet static
    address 192.168.1.100/24
    gateway 192.168.1.1
    bridge-ports enp0s1
    bridge-stp off
    bridge-fd 0

To apply changes, restart the networking service or reboot:

systemctl restart networking
# OR
reboot

Historical Notes#

This configuration was documented in March 2025. If the physical hardware (NIC) has changed since then, the bridge-ports value must be updated.
