Hairpinning.

Hairpinning allows two endpoints on the internal side of the NAT to communicate even if they only use each other's external IP addresses and ports.

Parameters

sm	NAT main.
b0	Vlib buffer.
ip0	IP header.
udp0	UDP header.
tcp0	TCP header.
proto0	NAT protocol.

static int snat_not_translate_fast ( snat_main_t *  sm, vlib_node_runtime_t *  node, u32  sw_if_index0, ip4_header_t *  ip0, u32  proto0, u32  rx_fib_index0  )

inlinestatic

Check if packet should be translated.

Packets aimed at outside interface and external addresss with active session should be translated.

Parameters

sm	NAT main
rt	NAT runtime data
sw_if_index0	index of the inside interface
ip0	IPv4 header
proto0	NAT protocol
rx_fib_index0	RX FIB index

Returns

0 if packet should be translated otherwise 1
