FREEBSD下如何在现有的ipnat.rules中添加端口映射

kinglongno1

小弟公司有台FREEBSD服务器做防火墙，做端口映射，用于对外，由于原来的网管大大走，最近小弟领导又要求添加一台机器做对外服务。
ipnat.conf配置如下
map xl0 192.168.0.0/16 -> 61.132.89.107/32
rdr xl0 61.132.89.99/32 port 80 -> 192.168.0.3 port 80
rdr xl0 61.132.89.99/32 port 20 -> 192.168.0.3 port 20
rdr xl0 61.132.89.99/32 port 21 -> 192.168.0.3 port 21
rdr xl0 61.132.89.99/32 port 25 -> 192.168.0.3 port 25
rdr xl0 61.132.89.99/32 port 110 -> 192.168.0.3 port 110
rdr xl0 61.132.89.99/32 port 3306 -> 192.168.0.3 port 3306
rdr xl0 61.132.89.99/32 port 3389 -> 192.168.0.3 port 3389
rdr xl0 61.132.89.99/32 port 5631 -> 192.168.0.3 port 5631
rdr xl0 61.132.89.99/32 port 5632 -> 192.168.0.3 port 5632
--------------------------------------------
添加新增端口
map xl0 192.168.0.0/16 -> 61.132.89.107/32
rdr xl0 61.132.89.99/32 port 80 -> 192.168.0.3 port 80
rdr xl0 61.132.89.99/32 port 20 -> 192.168.0.3 port 20
rdr xl0 61.132.89.99/32 port 21 -> 192.168.0.3 port 21
rdr xl0 61.132.89.99/32 port 25 -> 192.168.0.3 port 25
rdr xl0 61.132.89.99/32 port 110 -> 192.168.0.3 port 110
rdr xl0 61.132.89.99/32 port 3306 -> 192.168.0.3 port 3306
rdr xl0 61.132.89.99/32 port 3389 -> 192.168.0.3 port 3389
rdr xl0 61.132.89.99/32 port 5631 -> 192.168.0.3 port 5631
rdr xl0 61.132.89.99/32 port 5632 -> 192.168.0.3 port 5632
rdr xl0 61.132.89.99/32 port 8080 -> 192.168.0.5 port 80
rdr xl0 61.132.89.107/32 port 3000 -> 192.168.0.5 port 3389
然后执行 ipnat -f /etc/ipnat.conf出现
gate# ipnat -f ipnat.conf
1:ioctl(SIOCADNAT): File exists
2:ioctl(SIOCADNAT): File exists
3:ioctl(SIOCADNAT): File exists
4:ioctl(SIOCADNAT): File exists
5:ioctl(SIOCADNAT): File exists
6:ioctl(SIOCADNAT): File exists
7:ioctl(SIOCADNAT): File exists
8:ioctl(SIOCADNAT): File exists
9:ioctl(SIOCADNAT): File exists
10:ioctl(SIOCADNAT): File exist

不知道是否只需要这么配置？

--------------------------------------
请各位大哥帮忙，这是怎么回事？
