    Hi, Normally after ASA we connect directly to internet. But now we are required to use layer3 or router after an ASA. should I need to nat again on layer3 switch going to internet?

      No need to use NAT on both (Firewall and Router).
      My assumption is that the Router will be used as Internet Gateway, in that case it makes sense to have NAT implemented on the Gateway router, where as the Firewall will be used as a Policy/Filter device within your LAN environment.
