NetworkManager 1.54 Brings Support for Configuring Per-Device IPv4 Forwarding
Coming five months after NetworkManager 1.52, the NetworkManager 1.54 release adds support for configuring per-device IPv4 forwarding via the ipv4.forwarding connection property, support OCI baremetal in nm-cloud-setup, support for configuring the loopback interface in NetworkManager’s text-based UI (nmtui).
Also new in NetworkManager 1.54 is a “prefix-delegation” setting containing a subnet-id property that specifies the subnet to choose on the downstream interface when using IPv6 prefix delegation, as well as a new ovs-dpdk.lsc-interrupt property to configure the Link State Change (LSC) detection mode for OVS DPDK interfaces.
