I am trying to pass traffic from Mac A port 5800 to Mac B on port 5900 using pf.



The following is the rule I intend to use (maybe its wrong):



rdr pass inet proto tcp from any to any port 5800 -> 192.168.1.246 port 5900


but when I add it to /etc/pf.conf and run sudo pfctl -f /etc/pf.conf I get: 



$ sudo pfctl -f /etc/pf.conf
pfctl: Use of -f option, could result in flushing of rules
present in the main ruleset added by the system at startup.
See /etc/pf.conf for further details.

No ALTQ support in kernel
ALTQ related functions disabled
/etc/pf.conf:29: Rules must be in order: options, normalization, queueing, translation, filtering
pfctl: Syntax error in config file: pf rules not loaded


My config file is below:



#
# Default PF configuration file.
#
# This file contains the main ruleset, which gets automatically loaded
# at startup. PF will not be automatically enabled, however. Instead,
# each component which utilizes PF is responsible for enabling and disabling
# PF via -E and -X as documented in pfctl(8). That will ensure that PF
# is disabled only when the last enable reference is released.
#
# Care must be taken to ensure that the main ruleset does not get flushed,
# as the nested anchors rely on the anchor point defined here. In addition,
# to the anchors loaded by this file, some system services would dynamically 
# insert anchors into the main ruleset. These anchors will be added only when
# the system service is used and would removed on termination of the service.
#
# See pf.conf(5) for syntax.
#

#
# com.apple anchor point

nat-anchor "com.apple/*"
rdr-anchor "com.apple/*"
dummynet-anchor "com.apple/*"

rdr pass inet proto tcp from any to any port 5800 -> 192.168.1.246 port 5900
