1 Hi,guys!
2 I use iptables to let the PCs in the subnet to connect the internet outside.
3
4 And i write a simple script,but it doesn't work:
5
6 #!/bin/sh
7 iptables -F
8 #Define packets from Internet server to Intranet
9 iptables -A FORWARD -d 198.168.1.0/24 -i eth0 -j ACCEPT
10 #Define packets from Intranet to Internet
11 iptables -A FORWARD -s 198.168.1.0/24 -i eth1 -j ACCEPT
12
13
14 Here is the result of iptables -L:
15
16 # iptables -L
17 Chain INPUT (policy ACCEPT)
18 target prot opt source destination
19
20 Chain FORWARD (policy DROP)
21 target prot opt source destination
22 ACCEPT all -- anywhere 198.168.1.0/24
23 ACCEPT all -- 198.168.1.0/24 anywhere
24
25 Chain OUTPUT (policy ACCEPT)
26 target prot opt source destination
27
28
29 The eth0 here has the real ip,and the eth1 have a subnet ip:192.168.1.21.
30 How to fix this problem?All I need now is just to let my office
31 machine to use the internet!
32 Thanks in advanced!!
