Add/del NAT address to FIB.

Add the external NAT address to the FIB as receive entries. This ensures that VPP will reply to ARP for this address and we don't need to enable proxy ARP on the outside interface.

Parameters

addr	IPv4 address.
plen	address prefix length
sw_if_index	Interface.
is_add	If 0 delete, otherwise add.

Add static mapping.

Create static mapping between local addr+port and external addr+port.

Parameters

l_addr	Local IPv4 address.
e_addr	External IPv4 address.
l_port	Local port number.
e_port	External port number.
vrf_id	VRF ID.
addr_only	If 0 address port and pair mapping, otherwise address only.
sw_if_index	External port instead of specific IP address.
is_add	If 0 delete static mapping, otherwise add.
twice_nat	If value is TWICE_NAT then translate external host address and port. If value is TWICE_NAT_SELF then translate external host address and port whenever external host address equals local address of internal host.
out2in_only	If 1 rule match only out2in direction
tag	- opaque string tag

Parameters

sm	NAT main.
match	Address and port to match.
mapping	External or local address and port of the matched mapping.
by_external	If 0 match by local address otherwise match by external address.
is_addr_only	If matched mapping is address only
twice_nat	If matched mapping is twice NAT.
