Hi, Are you on latest? Could you please provide “show node counters” output.
Regards, Matus From: vpp-dev-boun...@lists.fd.io [mailto:vpp-dev-boun...@lists.fd.io] On Behalf Of Yuliang Li Sent: Saturday, October 28, 2017 8:48 PM To: vpp-dev@lists.fd.io Subject: [vpp-dev] nat44 address pool not fully used Hi, I use "nat44 add addr 10.1.1.2-10.1.1.254", in the hope that in2out traffic can use any of the source IP in the range. However, when I generate in2out traffic composing 65536 different internal source IP (with the same source port), only 10.1.1.2 is used for external source IP, and allocated 20162 port number. That means only 20162 internal IP get translated, while the rest are dropped. I am wondering why it does not allocate other addresses in the pool (e.g., 10.1.1.3)? Here are the output of show nat44 detail: 10.1.1.2 tenant VRF independent 0 busy udp ports 20162 busy tcp ports 0 busy icmp ports 10.1.1.3 tenant VRF independent 0 busy udp ports 0 busy tcp ports 0 busy icmp ports .... (all following shows 0 busy ports). Thanks, -- Yuliang Li PhD student Department of Computer Science Yale University
