# Configuration for the saned daemon

## Daemon options
# Port range for the data connection. Choose a range inside [1024 - 65535].
# Avoid specifying too large a range, for performance reasons.
#
# ONLY use this if your saned server is sitting behind a firewall. If your
# firewall is a Linux machine, we strongly recommend using the
# Netfilter nf_conntrack_sane connection tracking module instead.
