Hi,
I am using stable/1801 source build and have encountered a bug due to the CGNAT
plugin. When using deterministic CGN and using the nat { deterministic } option
in the startup.conf, if you apply normal nat44 rules, the interfaces do not
work as expected. And by initiating a ping command, vppctl crashes and exits
and with it, removes all its applied previous configuration from the CLI.
Here is a sample setup (loop0 and loop1 have been configured):
vpp# nat44 add interface address loop0
vpp# set interface nat44 in loop1 out loop0
vpp# nat44 add address 192.168.10.20 - 192.168.10.30
Now, when the ping command is run (IP address is of a tap interface initialized
in vpp), vpp crashes and all CLI configuration resets:
vpp# ping 192.168.100.2
root@xflow:~#
When the 'nat { deterministic }' statement is removed from the startup conf,
the issue is resolved and the setup behaves as intended.
