Wireless users not able to access internet through proxy

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
The forward IP is mentioned in /etc/bind/named.conf.options file as
forwarders {;
cat /etc/resolv.conf 
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 range.

Now I'll come to wireless network
wireless router details
dhcp range
The wireless users who are in network are neither able to ping 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
Internet--->Cisco load balancer192.168.0.1(DHCP range to>Wireless router with the same above IP and DHCP range.
Then I thought, may be I need to route network and ran
route add -net netmask gw dev eth1
command from the proxy server. Now all the users who comes in network and also network users are able to ping 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
route del -net netmask gw dev eth1
command and found the internet is working fine for only network users who are using wired connection.
So please help me in find out where I am wrong.
