what are the steps for a R-2 NAT to translate and communicate with a webserver from a client on the web?
1- client uses inside global address of webserver
2-R2 receives the packet on its outside interface, then checks and locates the destination address in its NAT table.
3-R2 replaces the inside global address with the inside local address of the web server and forwards the packet to the web server.
4-The web server uses the outside global address of the client as the destination address when responding.
5-R2 receives the packet from the web server. R2 checks the NAT table, then translates the source address into an inside global address and forwards the packet.
