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 Which method is used by a PAT-enabled router to send incoming packets to the correct inside hosts? It uses the destination TCP or UDP port number on the incoming packet. A network administrator configures the border router with
the command R1(config)# ip nat inside source list 4 pool corp. Which ACL is required to be configured in order for this command to function? an access list that is numbered 4 that defines the private addresses that are affected by NAT
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.
A network administrator wants to examine the active NAT translations on a border router. Which command would perform the task?
How many addresses will be available for dynamic NAT translation when a router is configured with the following commands?
What is the purpose of entering the command ip nat inside source static tcp 192.168.10.2 80 209.165.200.223 8080 at the global configuration prompt?
