Abstract
This disclosure describes systems, methods, and apparatus for using a NATTYPE module in a Linux kernel to carry out Full Cone NAT and address-restricted cone NAT while offloading NAT functionality to a hardware accelerator. The NATTYPE module can be configured to create a mapping between conntrack entries and NATTYPE entries and a conntrack module can be configured to update a NATTYPE entry when a conntrack entry is updated and the conntrack entry includes a mapping to a NATTYPE entry. Alternatively, a hardware accelerator controller can be configured to refresh conntrack entries as well as NATTYPE entries.
