See ISP gave me one public IP for serial int & one for gayeway. So I put that public ip to serial int & gave one privte ip to ethernet.
ip nat inside for ethernet
ip nat outside for serial intface
ip access-list 1 permit any
ip nat inside source list 1 interface Serial0/0 overload
ip route 0.0.0.0 0.0.0.0 gateway ip
This all I configured on router but internet is not working in LAN. Pls help me.

Router(config)#ip nat pool netview xxx.xxx.xxx.xxx(First IP from the pool ISP gae you) xxx.xxx.xxx.xxx(last IP from the pool ISP gave you) netmask (whatever IP mask ISP gave you)
(I used pool name as netview you can use any name u want to give)
Router(config)#access-list 1 permit any
Router(config)#ip nat inside source 1 (access-lisr number u have used 1) pool netview(which is assume u can write as per udefine above)
Remove this
ip nat inside source list 1 interface Serial0/0 overload
Add those 3 command and delete i told u and let me know how is it going.
paste your sh run after u have done config. u can hide ur IP address and password etc

Before proceeding, I highly recommend upgrading the IOS on that router as soon as possible.
You are running a very old IOS version that is exposed to several security vulnerabilities. Placing this device facing an internet connection wouldn't be ideal for this implementation.
Once you do that, follow the link I posted originally and all the commands listed on the link should work.

If ur router dont take pool command then ur configuration
ip nat inside for ethernet
ip nat outside for serial intface
ip access-list 1 permit any
ip nat inside source list 1 interface Serial0/0 overload
ip route 0.0.0.0 0.0.0.0 gateway ip
is correct instead of permit any u can try your Private IP address range.
ping from your LAN to gateway IP.
check sh ip nat translation command
One more thing you can check, is ISP have done configuration from ISP router to your router.
