# CLAT implements the client part of 464XLAT (RFC 6877), an
# architecture that provides IPv4 connectivity to hosts on IPv6-only
# networks.
#
# The default value for the connection property 'ipv4.clat' is still
# 'no'. Change it globally to 'auto' (1) so that CLAT gets enabled
# automatically when the network advertises a PREF64 and there is no
# native IPv4 configured (either because DHCPv4 option 108 was
# received or because there is no DHCPv4 server).
#
# See: https://fedoraproject.org/wiki/Changes/IPv6-Mostly_Support_In_NetworkManager

# Do not modify this file. You can hide/overwrite this file by
# creating "/etc/NetworkManager/conf.d/24-clat-auto.conf". You can
# also add configuration snippets with higher priority that override
# this setting (see `man 5 NetworkManager.conf`). Most importantly,
# this snippet only sets default values for the profile. You can
# explicitly set the value for each profile, so that this default
# value is not used.

# For example, on a particular profile/network set
#
#   $ nmcli connection modify "$PROFILE" ipv4.clat no
#
# to disable CLAT. This prevents the default from this file to take
# effect.
