Practical Guide To Virtual Networking on Linux
Linux Networking: Bridged and Routed VM Networking Scenario 1: Bridged Networking (Layer 2 Integration) Goal: VMs/containers appear as full LAN peers, get IPs from the LAN’s DHCP, and are reachable directly. Create a bridge interface (br0). Add the physical interface (e.g., eth0) to the bridge. Assign IP or DHCP to br0 only. eth0 should have no IP. Virtual interfaces (e.g., tap0) are also added to br0. Key Commands: sudo ip link add br0 type bridge sudo ip link set eth0 master br0 sudo ip link set br0 up sudo dhcpcd br0 No NAT, no subnetting. Full LAN access. ...
