You dont need NAT if you are assigning public IP directly to Server.

All you need is routing available.

by the on which interface your bandwidht is connected on this router?

Hello Sihanu,

yes without NAT, If there is OSI layer2 connectivity between the web server NIC and  router gi0/1 interface for example with a LAN switch in the middle

note: your prefix is on the internet so eBGP is fine.

Hope to help
