ConfigServer安全防火墙和端口转发

Question

我已经安装了"ConfigServer安全和防火墙“，但不知道如何做端口转发。有没有教程或者怎么做，或者有人能给我解释一下怎么做？

您可以使用"/etc/csf/csf.redirect“文件设置端口重定向。

# DNAT (redirect from one IP address to a different one):
# IPx|*|IPy|*|tcp/udp          - To IPx redirects to IPy
# IPx|portA|IPy|portB|tcp/udp  - To IPx to portA redirects to IPy portB
#
# DNAT examples:
# 192.168.254.62|*|10.0.0.1|*|tcp
# 192.168.254.62|666|10.0.0.1|25|tcp
#
# REDIRECT (redirect from port to a different one):
# IPx|portA|*|portB|tcp/udp    - To IPx to portA redirects to portB
# *|portA|*|portB|tcp/udp      - To portA redirects to portB
#
# REDIRECT examples:
# 192.168.254.60|666|*|25|tcp
# *|666|*|25|tcp
