请问伙伴们，自己的csf防火墙是不是出现了什么配置错误？
目前已经关闭了selinux和firewalld，自己的csf 配置如下：
###############################################################################
# SECTION:Initial Settings
###############################################################################
# Testing flag - enables a CRON job that clears iptables incase of
# configuration problems when you start csf. This should be enabled until you
# are sure that the firewall works - i.e. incase you get locked out of your
# server! Then do remember to set it to 0 and restart csf when you're sure
# everything is OK. Stopping csf will remove the line from /etc/crontab
#
# lfd will not start while this is enabled
TESTING = "0"
# The interval for the crontab in minutes. Since this uses the system clock the
# CRON job will run at the interval past the hour and not from when you issue
# the start command. Therefore an interval of 5 minutes means the firewall
# will be cleared in 0-5 minutes from the firewall start
TESTING_INTERVAL = "5"
# SECURITY WARNING
# ================
#
# Unfortunately, syslog and rsyslog allow end-users to log messages to some
# system logs via the same unix socket that other local services use. This
# means that any log line shown in these system logs that syslog or rsyslog
# maintain can be spoofed (they are exactly the same as real log lines).
#
# Since some of the features of lfd rely on such log lines, spoofed messages
# can cause false-positive matches which can lead to confusion at best, or
# blocking of any innocent IP address or making the server inaccessible at
# worst.
#
# Any option that relies on the log entries in the files listed in
# /etc/syslog.conf and /etc/rsyslog.conf should therefore be considered
# vulnerable to exploitation by end-users and scripts run by end-users.
#
# NOTE: Not all log files are affected as they may not use syslog/rsyslog
#
# The option RESTRICT_SYSLOG disables all these features that rely on affected
# logs. These options are:
# LF_SSHD LF_FTPD LF_IMAPD LF_POP3D LF_BIND LF_SUHOSIN LF_SSH_EMAIL_ALERT
# LF_SU_EMAIL_ALERT LF_CONSOLE_EMAIL_ALERT LF_DISTATTACK LF_DISTFTP
# LT_POP3D LT_IMAPD PS_INTERVAL UID_INTERVAL WEBMIN_LOG LF_WEBMIN_EMAIL_ALERT
# PORTKNOCKING_ALERT
#
# This list of options use the logs but are not disabled by RESTRICT_SYSLOG:
# ST_ENABLE SYSLOG_CHECK LOGSCANNER CUSTOM*_LOG
#
# The following options are still enabled by default on new installations so
# that, on balance, csf/lfd still provides expected levels of security:
# LF_SSHD LF_FTPD LF_POP3D LF_IMAPD LF_SSH_EMAIL_ALERT LF_SU_EMAIL_ALERT
#
# If you set RESTRICT_SYSLOG to "0" or "2" and enable any of the options listed
# above, it should be done with the knowledge that any of the those options
# that are enabled could be triggered by spoofed log lines and lead to the
# server being inaccessible in the worst case. If you do not want to take that
# risk you should set RESTRICT_SYSLOG to "1" and those features will not work
# but you will not be protected from the exploits that they normally help block
#
# The recommended setting for RESTRICT_SYSLOG is "3" to restrict who can access
# the syslog/rsyslog unix socket.
#
# For further advice on how to help mitigate these issues, see
# /etc/csf/readme.txt
#
# 0 = Allow those options listed above to be used and configured
# 1 = Disable all the options listed above and prevent them from being used
# 2 = Disable only alerts about this feature and do nothing else
# 3 = Restrict syslog/rsyslog access to RESTRICT_SYSLOG_GROUP ** RECOMMENDED **
RESTRICT_SYSLOG = "0"
# The following setting is used if RESTRICT_SYSLOG is set to 3. It restricts
# write access to the syslog/rsyslog unix socket(s). The group must not already
# exists in /etc/group before setting RESTRICT_SYSLOG to 3, so set the option
# to a unique name for the server
#
# You can add users to this group by changing /etc/csf/csf.syslogusers and then
# restarting lfd afterwards. This will create the system group and add the
# users from csf.syslogusers if they exist to that group and will change the
# permissions on the syslog/rsyslog unix socket(s). The socket(s) will be
# monitored and the permissions re-applied should syslog/rsyslog be restarted
#
# Using this option will prevent some legitimate logging, e.g. end-user cron
# job logs
#
# If you want to revert RESTRICT_SYSLOG to another option and disable this
# feature, change the setting of RESTRICT_SYSLOG and then restart lfd and then
# syslog/rsyslog and the unix sockets will be reset
RESTRICT_SYSLOG_GROUP = "mysyslog"
# This options restricts the ability to modify settings within this file from
# the csf UI. Should the parent control panel be compromised, these restricted
# options could be used to further compromise the server. For this reason we
# recommend leaving this option set to at least "1" and if any of the
# restricted items need to be changed, they are done so from the root shell
#
# 0 = Unrestricted UI
# 1 = Restricted UI
# 2 = Disabled UI
RESTRICT_UI = "1"
# Enabling auto updates creates a cron job called /etc/cron.d/csf_update which
# runs once per day to see if there is an update to csf+lfd and upgrades if
# available and restarts csf and lfd
#
# You should check for new version announcements at http://blog.configserver.com

# colon (e.g. 30000:35000).
# Some kernel/iptables setups do not perform stateful connection tracking

# to 0 to reconfigure csf as a static firewall.
#
# As connection tracking will not be configured, applications that rely on it
# will not function unless all outgoing ports are opened. Therefore, all

#
# If you allow incoming DNS lookups you may need to use the following
# directive in the options{} section of your named.conf:
#
# query-source port 53;
#
# This will force incoming DNS traffic only through port 53
#
# Disabling this option will break firewall functionality that relies on
# stateful packet inspection (e.g. DNAT, PACKET_FILTER) and makes the firewall
# less secure
#
# This option should be set to "1" in all other circumstances

IPV6_ICMP_STRICT = "0"

#
# A workaround has been added for CentOS/RedHat v5 and custom kernels that do
# not support IPv6 connection tracking by opening ephemeral port range
# 32768:61000. This is only applied if IPV6_SPI is not enabled. This is the
# same workaround implemented by RedHat in the sample default IPv6 rules
#
# As connection tracking will not be configured, applications that rely on it

# Specify the the two-letter ISO Country Code(s). The iptables rules are for

# WARNING: These lists are never 100% accurate and some ISP's (e.g. AOL) use

# overheads and could render the server inaccessible in some circumstances. For
# this reason (amongst others) we do not recommend using these options
