From 86cb96ae1861908ea1fa6d1b0cbd1832661c8571 Mon Sep 17 00:00:00 2001 From: Charles Surett Date: Fri, 2 Apr 2021 17:40:02 -0400 Subject: interfaces: dhcp-client: T3454: add reject option Sometimes a modem might give a local IP before it retrieves a WAN IP. This can be an issue with failover routes, since the default route will get overridden.
