From 6961d912061c81b7a444e7c00163ae240e318c42 Mon Sep 17 00:00:00 2001 From: Paul Holzinger Date: Thu, 27 Jan 2022 15:13:55 +0100 Subject: network create: allow multiple subnets podman network create --subnet, --gateway and --ip-range can now be specified multiple times to join the network to more than one subnet. This is very useful if you want to use a dual stack network and assign a fixed ipv4 and ipv6 subnet. The order of the options is important here, the first --gateway/--ip-range will be assigned to the first subnet and so on.
