I have this very simple config:

cli-listen /run/vpp/cli.sock
gid vpp
startup-config /etc/vpp/initial_setup.conf
poll-sleep-usec 100
}
api-trace {
on
}
api-segment {
gid vpp
}
socksvr {
default
}
cpu {
}
buffers {
buffers-per-numa 512000
default data-size 4096
}
dpdk {
dev default {
num-rx-queues 3
num-tx-queues 3
num-rx-desc 512
num-tx-desc 512
rss-queues 0,2,5-7
}
dev 0000:01:00.0 {
name wanport
}
dev 0000:03:00.0 {

}
}
plugins {

}
logging {

set interface nat44 in loop1 out wanport
comment { Route ssh (TCP 22) to the untag Linux interface }
nat44 add static mapping local 192.168.2.2 22 external wanport 22 tcp
When starting vpp manually I get an error on NAT44:
guestport.1000
loop0
loop1
tap0
tap1
nat44 add interface address: add wanport address failed
This same config works on CentOS with vpp 20.09 but failt with v22.06-rc1
wanport did get an IP via DHCP.
Any clues ?
