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
addrIPv4 address.
plenaddress prefix length
sw_if_indexInterface.
is_addIf 0 delete, otherwise add.

Add static mapping.

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

Parameters
l_addrLocal IPv4 address.
e_addrExternal IPv4 address.
l_portLocal port number.
e_portExternal port number.
vrf_idVRF ID.
addr_onlyIf 0 address port and pair mapping, otherwise address only.
sw_if_indexExternal port instead of specific IP address.
is_addIf 0 delete static mapping, otherwise add.
twice_natIf 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_onlyIf 1 rule match only out2in direction
tag- opaque string tag

Match NAT44 static mapping.

Parameters
smNAT main.
matchAddress and port to match.
mappingExternal or local address and port of the matched mapping.
by_externalIf 0 match by local address otherwise match by external address.
is_addr_onlyIf matched mapping is address only
twice_natIf matched mapping is twice NAT.
lbIf matched mapping is load-balanced.
Returns
0 if match found otherwise 1.
