iptables+Squid做透明代理出现问题

orphen

Squid已经配置好了，通过设定浏览器的代理可以上网，没有问题。我现在这个帖子就是在设定代理服务器的情况下写的。
iptables的设置如下

1. [root@GW ~]# iptables-save
   
2. # Generated by iptables-save v1.2.11 on Fri Sep 23 05:55:21 2005
   
3. *filter
   
4. :INPUT ACCEPT [1682024:1154186586]
   
5. :FORWARD ACCEPT [599618:414869505]
   
6. :OUTPUT ACCEPT [1661188:1241663149]
   
7. -A INPUT -i ppp0 -p tcp -m tcp --dport 1:1024 -j DROP
   
8. -A INPUT -i ppp0 -p udp -m udp --dport 1:1024 -j DROP
   
9. -A INPUT -i eth0 -p udp -m udp --dport 1:1024 -j DROP
   
10. -A INPUT -i eth0 -p tcp -m tcp --dport 1:1024 -j DROP
    
11. COMMIT
    
12. # Completed on Fri Sep 23 05:55:21 2005

14. *nat
    
15. :PREROUTING ACCEPT [4161:350794]
    
16. :POSTROUTING ACCEPT [6415:384420]
    
17. :OUTPUT ACCEPT [6415:384420]
    
18. -A PREROUTING -i eth1 -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 3128
    
19. -A POSTROUTING -s 192.168.0.0/255.255.255.0 -j MASQUERADE
    
20. COMMIT
    
21. # Completed on Fri Sep 23 05:55:21 2005

也查看了一些关于透明代理的文章，没发现有什么区别啊？
但是访问时就会出现[PHP]ERROR
The requested URL could not be retrieved
While trying to retrieve the URL: /
The following error was encountered:
Invalid URL
Some aspect of the requested URL is incorrect. Possible problems:
Missing or incorrect access protocol (should be `http://'' or similar)
Missing hostname
Illegal double-escape in the URL-Path
Illegal character in hostname; underscores are not allowed
Your cache administrator is root.

怎么回事？？

注明：
我的我的网关服务器为RHEL AS4
Selinux已经关闭
不使用透明代理时，直接通过iptables的MASQUERADE上网没有问题

哪位帮忙看看哦
