Creating Dynamic Inside Source Translation Rules

Use the ip nat inside source list command to create a dynamic inside source translation rule. This command creates a translation rule that:

• Translates inside local source addresses to inside global addresses when packets from the inside network are routed to the outside network
• Translates outside local source addresses to outside global addresses when packets from the outside network are routed to the inside network.
• Use the overload keyword to specify that the translation create NAPT entries (protocol, port, and address) in the NAT table.

The no version of this command removes the dynamic translation rule, but does not remove any previously created translations (resulting from the rule evaluation) from the translation table. To remove active translations from the translation table, see Clearing Dynamic Translations.

ip nat inside source list

• Use to create dynamic translation rules that specify when to create a translation for a source address when routing a packet from the inside network to the outside network.
• Example

  host (config) #ip nat inside source list translation1 pool pool1

• Use the overload keyword to specify that the translation create extended entries (protocol, port, and address) in the translation table for NAPT.
• Use the no version to remove the dynamic translation rule; this command does not remove any dynamic translations from the translation table.
• See ip nat inside source list.
