snat add static mapping local tcp|udp|icmp <addr> [<port>] external <addr> [<port>] [vrf <table-id>] [del].
vpp# snat add static mapping
Static mapping allows hosts on the external network to initiate connection
to to the local network host.
To create static mapping between local host address 10.0.0.3 port 6303 and
external address 4.4.4.4 port 3606 for TCP protocol use:
vpp# snat add static mapping local tcp 10.0.0.3 6303 external 4.4.4.4 3606
If not runnig "static mapping only" S-NAT plugin mode use before:
vpp# snat add address 4.4.4.4
To create static mapping between local and external address use:
vpp# snat add static mapping local 10.0.0.3 external 4.4.4.4
Declaration: add_static_mapping_command (src/plugins/snat/snat.c line 2259)
Implementation: add_static_mapping_command_fn.
snat deterministic add in <addr>/<plen> out <addr>/<plen> [del].
vpp# snat deterministic add
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.
To create deterministic mapping between inside network 10.0.0.0/18 and
outside network 1.1.1.0/30 use:
# vpp# snat deterministic add in 10.0.0.0/18 out 1.1.1.0/30
Declaration: snat_det_map_command (src/plugins/snat/snat.c line 3220)
Implementation: snat_det_map_command_fn.
snat deterministic forward <addr>.
vpp# snat deterministic forward
Return outside address and port range from inside address for deterministic
NAT.
To obtain outside address and port of inside host use:
vpp# snat deterministic forward 10.0.0.2
1.1.1.0:<1054-1068>
Declaration: snat_det_forward_command (src/plugins/snat/snat.c line 3282)
Implementation: snat_det_forward_command_fn.
snat deterministic reverse <addr>:<port>.
vpp# snat deterministic reverse
Return inside address from outside address and port for deterministic NAT.
To obtain inside host address from outside address and port use:
#vpp snat deterministic reverse 1.1.1.1:1276
10.0.16.16
Declaration: snat_det_reverse_command (src/plugins/snat/snat.c line 3347)
Implementation: snat_det_reverse_command_fn.
snat ipfix logging [domain <domain-id>] [src-port <port>] [disable].
vpp# snat ipfix logging
To enable SNAT IPFIX logging use:
vpp# snat ipfix logging
To set IPFIX exporter use:
vpp# set ipfix exporter collector 10.10.10.3 src 10.10.10.1
Declaration: snat_ipfix_logging_enable_disable_command (src/plugins/snat/snat.c line 2390)
