Các câu lệnh NAT có thể phân chia như sau, trong đó ip nat inside thường được dùng hơn vì nếu dùng ip nat outside thì trong 1 số trường hợp cần phải cấu hình thêm static route (do traffic từ inside ra outside được xử lý routing trước rồi mới NAT).

Picture 8: Router NAT Network Address Translation Table. Both inside local IP addresses 10.0.0.1 and 10.0.0.2 are mapped to a single inside global IP address 155.0.1.1, with different source TCP ports 42264 and 50887, respectively. PAT however, has not translated the source port for both connections.

Most of us are familiar with the ip nat inside source command because we often use it to translate private IP addressses on our LAN to a public IP address we received from our ISP. 2019-04-24 · IP nat inside source static. Use. This command is used to specify a map between a specific IP address (and port number if required). Used when you must use only a certain IP address or port such as SMTP. Syntax. R1(config)#ip nat inside source static OR ip nat inside source static 192.168.10.2 172.16.10.2 as you rightly say R3 needs to have a route for 172.16.10.2 pointing to R2. So 192.168.10.2 sends a packet to 10.10.10.2, R2 receives the packet does a route lookup for 10.10.10.2, sees it is reachable via it's outside interface, the packet is forwarded to the outside interface and then NAT is done changing the source IP to 172.16.10.2. 1.

Used when you must use only a certain IP address or port such as SMTP. Syntax. R1(config)#ip nat inside source static OR Response comes in, first routing decision - NAT table entry matched!

Command. IP nat inside source list. Use. This command is used to specify an access-list that matches which IPs should be translated. Syntax. R1(config)#ip nat

This is how the NAT order of operations works on the inside. So now it's clear: IOS first tries to route packet to 155.1.13.2 - which is the same interface as it came in.. therefore the inside->outside translation never occurs! 1.
