Detailed Description

deterministic NAT

Definition in file nat_det.c.

Function Documentation

int snat_det_add_map	(	snat_main_t *	sm,
		ip4_address_t *	in_addr,
		u8	in_plen,
		ip4_address_t *	out_addr,
		u8	out_plen,
		int	is_add
	)

Add/delete deterministic NAT mapping.

Create bijective mapping of inside address to outside address and port range pairs, with the purpose of enabling deterministic NAT to reduce logging in CGN deployments.

Parameters

sm	SNAT main.
in_addr	Inside network address.
in_plen	Inside network prefix length.
out_addr	Outside network address.
out_plen	Outside network prefix length.
is_add	If 0 delete, otherwise add.
