LinuxQuestions.org - Wireless users not able to access internet through proxy

Hi..everybody.
I could successfully configured transparent proxy using this link. Everything is working fine for only those users who are using wired connection. DNS and DHCP servers also is configured in the same proxy server. Here is the server setup details

Code:

eth0=192.168.1.2/24(Internet)

gateway=192.168.1.1

eth1=192.168.0.1/24(LAN)

The forward IP is mentioned in /etc/bind/named.conf.options file as

Code:

forwarders {

        192.168.1.1;

        };

Code:

cat /etc/resolv.conf 

seach ourdomain_name.com.

nameserver 192.168.0.1

The wired clients are able to ping internal and external domains. And mailclients, FTP, and everything is working fine for wired users who are in the 192.168.0.0 range.

Now I'll come to wireless network

Code:

wireless router details

IP 192.168.0.236/24

g/w 192.168.0.1

dns 192.168.0.1

dhcp range 192.168.1.200 192.168.1.254

The wireless users who are in 192.168.1.0 network are neither able to ping 192.168.0.1 nor external domains. But if they go without proxy then the wireless router details will be same and the internet will be working fine for the wireless users. At that time the setup will be as below

Code:

Internet--->Cisco load balancer192.168.0.1(DHCP range 192.168.0.200 to 192.168.0.254)--->Wireless router with the same above IP and DHCP range.

Then I thought, may be I need to route 192.168.1.0 network and ran

Code:

route add -net 192.168.1.0 netmask 255.255.255.0 gw 192.168.0.1 dev eth1

command from the proxy server. Now all the users who comes in 192.168.1.0 network and also 192.168.0.0 network users are able to ping 192.168.0.1 and also some other internal domains but not to external domains. Then I checked from the server, now from the server also neither able to ping nor nslookup to external domains. Then I deleted the entry using

Code:

route del -net 192.168.1.0 netmask 255.255.255.0 gw 192.168.0.1 dev eth1

command and found the internet is working fine for only 192.168.0.0 network users who are using wired connection.
So please help me in find out where I am wrong.
