Hi Kumarjeet

All you need is the (nat-control) command which by default is off.

Hi,

If you can browse some sites and not others, I would guess the problem is either inspection on the http which you will have to disable in this case or remove the tcp-mss policy by following the procedure in the following link...

I recommend you use the logging feature in ASDM and have it filter and show you only communications to your computer and then you will see what is being blocked so we can give you a better answer.
