+# Config template for: firewall conntrack-table-size
+# 
+# Sets the size of the TCP connection tracking table in the netfilter
+# nf_conntrack module, which is used by firewall and NAT.  The size of
+# this table determines how many TCP connections can be simultaneously
+# tracked.  If new connections arrive and the table is full, older
+# connections will be dropped out of the table.  System administrators
+# must set the connection tracking table size based on the number of
+# connections they expect their system to track.  The connection
+# tracking table consumes kernel memory, so the size selected should
+# be no larger than necessary.
