Hi Nathan, We hope to use CNAT to play the role of kube-proxy. Since our applications specifies namespaces, so we want CNAT rules to take effect in different FIB tables.Best Regards,Yacan

Greetings,
I am running into performance issues passing TCP traffic through VPP. My
network of docker containers achieves ~25 Gbps using iperf when VPP is
disabled. When running VPP on the edge nodes of my network, that same
throughput throttles back to ~300 Kbps. I can see the TCP packets trav

I meant VPP 21.01; links are pointing there, it is just a typo.

In CSIT, we have one testbed type (3-node Haswell)
with older cards (Cisco VIC 1385 and even Cisco VIC 1227),
but we are running tests on those very rarely

larger test selection on fewer NICs).

Sorry, I wasn't clear. VPP IPv4 supports IP update checksum. The IPv6
header has no checksum. But why doesn't VPP support update checksum for
layer-4, e.g., udp/tcp/icmp? A routed data plane may reply to certain
messages (e.g., icmp, tcp, gtpu echo) in the data plane and such replies
could use a
VPP IPv4 supports update checksum but IPv6 does not. Why is that? IPv6
only had a compute and verify checksum.

There are 2 cases here :

Hello Filip,
I checked it out, take a look at show nat44 deterministic mapping:

Hi Yacan,
There is no particular reason, just that the code for CNAT is quite new, and
we never implemented vrf support. I don't see any blocker to add it if you
need it.
What is the use-case you would like to support ? By specifying a table ID,
do you
mean for matching traffic ? Also for the rew
Hi,
Yes you should be able to use the command on v20.05 vpp build.
I don't think the Out of ports error is timeout related. I would check mapping
configurations.

Hello Marcos,
I am currently working on updating docs for all NAT plugins. These docs &
introduction should be than located in the appropriate plugin directory in
markdown file.
The wiki docs is outdated.
To use DET44 nat (it is a separate plugin now) you would have to first enable
the plugin

Hi, We observed that CNAT translation rule now can only be set in the default table for v4 and v6. Why is there such a restriction ? Best Regards,Yacan
