问题详细补充:
# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
DROP tcp -- anywhere anywhere tcp dpts:0:1023
DROP udp -- anywhere anywhere udp dpts:0:1023
DROP tcp -- anywhere anywhere tcp flags:FIN,SYN,R ST,ACK/SYN
DROP icmp -- anywhere anywhere icmp echo-request
Chain FORWARD (policy DROP)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Chain RH-Firewall-1-INPUT (0 references)
...........................
但查看/etc/sysconfig/iptables配置文件,FORWARD policy 也为ACCEPT,所以只有增加iptables -t filter -P FORWARD ACCEPT 或 restart iptables ,FORWARD 's policy is ACCEPT.
Why & How ??? |
