如何运行iptables脚本
我的系统是Redhat 9.0,我从别处移植了一个iptables脚本,但运行时总提示:
[root@Test-Proxt root]#./setiptables
-bash: ./setiptables: 没有那个文件或目录
这个脚本在7.0系统上可以运行,请问是什么原因?如何处理?
附上脚本内容:
#!/bin/sh
configuration options
LAN_IP_RANGE="192.169.10.0/24"
LAN_IP="192.169.10.1"
LAN_BCAST_ADRESS="192.169.10.255"
LAN_IFACE="eth1"
INET_IP="202.111.44.199"
INET_IFACE="eth0"
LO_IP="127.0.0.1"
LO_IFACE="127.0.0.1"
IPTABLES="/sbin/iptables"
#echo "Starting iptables rules..."
Load all required IPTables modules
Needed to initially load modules
/sbin/depmod -a
Adds some iptables targets like LOG, REJECT and MASQUARADE.
/sbin/modprobe ipt_LOG
/sbin/modprobe ipt_MASQUERADE
/sbin/modprobe ip_tables
/sbin/modprobe ip_nat_ftp
/sbin/modprobe ip_conntrack_ftp
Delete old PREROUTING chain
$IPTABLES -t nat -F PREROUTING
#------------------------------------------------------------------------------
$IPTABLES -t nat -A PREROUTING -s 192.168.0.0/16 -j DROP
$IPTABLES -t nat -A PREROUTING -s 10.0.0.0/8 -j DROP
$IPTABLES -t nat -A PREROUTING -s 172.16.0.0/12 -j DROP
#------------------------------------------------------------------------------
Delete old POSTROUTING chain
$IPTABLES -t nat -F POSTROUTING
MASQ to INET_IFACE
$IPTABLES -t nat -A POSTROUTING -o $INET_IFACE -j MASQUERADE
set SNAT
$IPTABLES -t nat -A POSTROUTING -s $LAN_IP_RANGE -j SNAT --to $INET_IP
Delete old INPUT chain
$IPTABLES -F INPUT
Drop ports in PREROUTING
#$IPTABLES -A INPUT -p tcp -i $INET_IFACE -d $INET_IP --dport 10021 -j RETURN
port:22
$IPTABLES -A INPUT -p tcp -i $INET_IFACE -s 202.111.44.200/32 -d $INET_IP --dport 22 -j ACCEPT
$IPTABLES -A INPUT -p tcp --dport 22 -j DROP<b
