首先我iptable設定如下
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i eth0 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 25 -j ACCEPT
-A FORWARD -m state --state ESTABLISHED,RELATED -j ACCEPT
-A FORWARD -p icmp -j ACCEPT
-A FORWARD -i eth0 -j ACCEPT
-A FORWARD -o eth0 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT
我想問一下 我default INPUT policy 是 ACCEPT, 但是我想要連 80 port
卻會被擋掉而連 ssh 卻可以, 我應設定如果沒設定rule就應該是ACCEPT壓
但是怎還會被擋掉 希望有人可以幫忙解答
感謝
