删除 所有策略
rmfilt -v 4 -n all
1、查看所有deny的策略，注意rule no 和端口地址

2 删除需要deny的策略代码(注意删除了一条策略后，会自动向前补一条。如果要删除需要重新查看后删除)
2,
root@ODS_DB1[/tmp/ibmsupt]# rmfilt -v 4 -n 242
Filter rule 242 for IPv4 has been removed successfully.
3、添加路由策略 注意IP地址 掩码 端口
3,
genfilt -v 4 -a P -s 192.168.10.141 -m 255.255.255.255 -d 192.168.10.191 -M 255.255.255.255 -o gt -p 1023 -O eq -P 50000
genfilt -v 4 -a P -s 192.168.10.143 -m 255.255.255.255 -d 192.168.10.191 -M 255.255.255.255 -o gt -p 1023 -O eq -P 50000
genfilt -v 4 -a P -s 192.168.10.141 -m 255.255.255.255 -d 192.168.10.189 -M 255.255.255.255 -o gt -p 1023 -O eq -P 50000
genfilt -v 4 -a P -s 192.168.10.143 -m 255.255.255.255 -d 192.168.10.189 -M 255.255.255.255 -o gt -p 1023 -O eq -P 50000
4、添加 deny 路由规则和端口
4,
genfilt -v 4 -a D -s 0.0.0.0 -m 0.0.0.0 -d 192.168.10.191 -M 255.255.255.255 -o gt -p 1023 -O eq -P 50000
genfilt -v 4 -a D -s 0.0.0.0 -m 0.0.0.0 -d 192.168.10.189 -M 255.255.255.255 -o gt -p 1023 -O eq -P 50000
5、更新路由规则
5,
mkfilt -v 4 -u
6、查看时候生效(包含deny)
6,
lsfilt |grep -p 192.168.10.141
lsfilt |grep -p 0.0.0.0
121 permit 192.168.10.0 255.255.255.224 136.5.9.51 255.255.255.255 yes all gt 1 eq 2201 both both no all packets 0 all 0 none
122 permit 192.168.10.245 255.255.255.255 136.5.9.51 255.255.255.255 yes all gt 1023 eq 2201 both both no all packets 0 all 0 none
123 deny 0.0.0.0 0.0.0.0 136.5.9.51 255.255.255.255 yes all gt 1 eq 2201 both both no all packets 0 all 0 none

124 deny 0.0.0.0 0.0.0.0 136.5.9.51 255.255.255.255 yes all gt 1 eq 2201 both both no all packets 0 all 0 none
genfilt -v 4 -n 123 -a P -s 192.168.10.178 -m 255.255.255.0 -d 136.5.9.51 -M 255.255.255.255 -o gt -p 1023 -O eq -P 2201
ps:如果需要一个段的IP
