# Shorewall -- /usr/share/shorewall/macro.NTPbrd
|
|
#
|
|
# This macro handles NTP traffic including replies to Broadcast NTP traffic.
|
|
#
|
|
# It is recommended only to use this where the source host is trusted -
|
|
# otherwise it opens up a large hole in your firewall because
|
|
# Netfilter doesn't track connections for broadcast traffic.
