thanks you guys ,but bridging is risky
i made new bridge connection ,bind lan and connect
D-Link router ,i setup dlink ( their was no option to set
mac address initially ,so after setup and went to internet connection and then cloned the mac address, but my router immediately went auth fail
after waiting for several hours ,i went to office and told what i did, as expected he dont know about bridge mode, he told technician on call to go my home
he came after 2 hours ,and asked me what i did,he immediately called someone and told that my router went blacklisted ,and asked them to remove black listed
he told me ,you should have asked me ,i can do it for you ,but he told since router is old ,so you will not see any advantage ,you need new router
i asked my router blacklisted
he said , whenever server see two different mac address ,it blocks connection ( known as sorting in their language )
after whole night and half day passed ,when my connection doest went up ,i called him again ,he came with another router ,and changed it and took my router for testing ( because i told them why i was trying to setup bridge connection )
he will come again, i hope everything will be good ,otherwise i have to leave bsnl
suggestion - who ever trying bridge mode ,please make sure you cloned mac address before trying to connect ,dont let your router make connection with default mac address
even i surprised that isp was to fast for blacklisting my router ,whereas i see many one here saying they tried many times ,still no problem
