Fully installed and configured CentOS 6.3 with GNOME (2.28.2) installed from Live CD x84_64 for demonstration purpose of Asterisk PBX.<br />

<br />
There might be same issue with some other websites but I have not seen that. Same Websites are opening without any problem on MS Windows 7 environment. I <br />
<br />
could not find any information regarding this issue on any Linux Forums either.<br />
These websites could not be loaded on both wired and wireless network under Linux environment. <br />
Same Linux machine opens the above mentioned website without any problems if using some other Network. <br />
Network: D-link DI-524 Wireless Router (IP:192.168.0.1)+ WiMax DSL Modem (IP: 192.168.15.1). Modem is connected to router through WAN port.<br />
These websites are not opening on any other CentOS machines as well in this network. <br />
Older distributions of Linux (Fedora Core 10, Core 11) work fine on the same network.<br />
I have changed the configuration files accordingly to overcome this problem but in no use.<br />
As shown in /etc/resolve.conf , it show two IPs , nameserver 192.168.15.1 & 192.168.0.1.<br />
If I connect the Linux Machine directly throw network cable to my WiMax modem, everything starts working fine. This time if I check the /etc/resolve.conf <br />
<br />
file there will only be “nameserver 192.168.15.1”. I made changes to /etc/sysconfig/network-scriept/ifcfg-Auto_Wlan01 but nothing worked. <br />
Conclusion: There is no problem in installation as it is working fine on all other networks where there is single device (builtin modem + router) but with <br />
<br />
this particular network, where there is a combination of D-link Router DI-524 and WiMax DSL Modem or when there are two nameserver addresses in <br />
<br />
/etc/resolve.conf file. <br />
<br />
Can I call it a bug in kernel in new Linux Versions, that it is not handling two addresses or these two particular addresses (192.168.15.1 & 192.168.0.1). <br />
<br />
But I cannot understand, as I have mentioned about that older Linux distributions are working fine on the same network. If I connect my linux machine <br />
<br />
directly to WiMax modem using wire, everything start working. And as well as there is no problem if working under MS Windows environment. <br />
<br />
<br />
Some configuration files are given below.<br />
