#
# MACLIST caching
#
# If your iptables and kernel support the "Recent Match" (see the output of
# "shorewall check" near the top), you can cache the results of a 'maclist'
# file lookup and thus reduce the overhead associated with MAC Verification
# (/etc/shorewall/maclist).
#
# When a new connection arrives from a 'maclist' interface, the packet passes
# through then list of entries for that interface in /etc/shorewall/maclist. If
# there is a match then the source IP address is added to the 'Recent' set for
# that interface. Subsequent connection attempts from that IP address occuring
# within $MACLIST_TTL seconds will be accepted without having to scan all of
# the entries. After $MACLIST_TTL from the first accepted connection request,
# the next connection request from that IP address will be checked against
# the entire list.
#
# If MACLIST_TTL is not specified or is specified as empty (e.g,
# MACLIST_TTL="" or is specified as zero then 'maclist' lookups will not
# be cached.
