VPP always generates new random mac address for outgoing IPs.
Weird but sometimes their are totally dofferent:

02:fe:0d:30:68:36 18.31.0.2

Setting mac address manually in config do the job.

Looks like always setting mac address manually in config do the job.

Hi,
I've go very simple config for NAT44:
create interface rdma host-if enp1s0f0 name rdma-0
create sub-interfaces rdma-0 934
create sub-interfaces rdma-0 935
set interface ip address rdma-0.934 10.0.100.10/31
set interface ip address rdma-0.935 18.31.0.1/25
set interface state rdma-0 up
set interface state rdma-0.934 up
set interface state rdma-0.935 up
ip route add 10.0.0.0/8 via 10.0.100.11 rdma-0.934
ip route add 0.0.0.0/0 via 18.31.0.126 rdma-0.935
nat44 enable sessions 900000
set int nat44 in rdma-0.934 out rdma-0.935
nat44 add address 18.31.0.2-18.31.0.124
In case of server reboot or vpp process failure, nat doesn't work for
relatively long time period.
Moreover some servers starts working where others are not yet.
After 10-20 minutes it start work as expected.
Ping is working to private servers from vpp process.
Vpp is builded from source (vpp v21.10-rc0~361-g5aa06abf2) but work delay the
same in repo version.
VPP starts create some sessions but it simply not working from the PC side.
Below some outputs:
vpp# show nat44 sessions
