Hi Ashwini,
I am sorry I wasn't able to respond earlier.
Basically you have multiple issues here. You are not configuring NAT
outside address as suggested by yangbin. Though you can ignore the default
route comment you don't need to worry about this to make the example work.
Also output-feature
There are 2 types of NAT implementation.
when you use "in" and "out" at same time. it's PRE-ROUTING NAT
when you use "out" with "output-feature" keyword . it's POST-ROUTING NAT.
no matter what type of NAT you choose to use, there are 2 import thing you
need to do,
first,enable nat
second,make
I would advise trying command below:
nat44 plugin enable sessions 63000
nat44 forwarding enable
set nat timeout udp 3000 tcp-established 7440 tcp-transitory 2400 icmp 600
set interface nat44 out {wan1} output-feature
nat44 add static mapping tcp local 192.168.1.20 external 4.4.4.4
nat44 add
Hi Ashwini,
Thank you. I am looking into it.
Best regards,
Filip Varga

Hi Filip,
Please let me know your thoughts on what the issue is and how it can be
resolved. We are working towards a demo and hoping to use VPP in it. This is
kind of a blocker right now.

Hi Filip,
Please also find attached the VPP trace for tcp data when nat44 forwarding is
disabled.

Hi Filip,
The VPP trace for dpdk-input in last email incuded TCP requests from HOST C to
Host A by iperf3 server and client via VPP.
Please find below the vpp trace for dpdk-input for ICMP ping requests from Host
C to Host A via VPP. As mentioned above this work. Incuded trace for comparison.
Hi Filip ,
Added the following NAT Config
vpp# clear trace
vpp# trace add dpdk-input 100
vpp# nat44 plugin enable sessions 63000
vpp# nat44 forwarding enable
vpp# set interface nat44 in lan
vpp# set interface nat44 out wan1920
vpp# set interface nat44 out wan1930
vpp# nat44 add static mapping
Hi Ashwini,
Can you also please send me a packet trace from VPP ?
Thank you.
Best regards,

Hi Filip,
I did try your recommendations . Updated NAT config to as below
Test Case 1
nat44 plugin enable sessions 63000
nat44 forwarding enable
set nat timeout udp 3000 tcp-established 7440 tcp-transitory 2400 icmp 600
set interface nat44 in lan
set interface nat44 out wan1
set interface nat44
Hi Ashwini,
I will look into your issue. But for reference I would advise against using
a combination of inside interface and output-feature.
OUTPUT-FEATURE or in other words output interface already contains
nat44-inside node. Output-feature does postrouting - after ip4-lookup node
decides
Hi All,
I am trying to make NAT44 ed work for TCP/UDP traffic on my setup. My setup is
as follows
Host A, Host B <-VPP <- Host C
Host A , Host B and Host C can communicate to each other via VPP. The VPP
container has two interfaces. My current version of VPP is
13 matches
