Abstract:
A system administrator can specify NAT mappings to perform NAT translations in a switch. The administrator can specify an ACL to filter packets to be translated. Filter rules generated from the ACL are stored in a first memory store in a switch and NAT rules generated from the NAT mappings are stored in a second memory store separate from the first memory store. When a packet matches one of the filter rules a tag that identifies the ACL is associated with the packet. When the tagged packet matches one of the NAT rules, the packet is translated according to the matched NAT rule.
