ans test dpdk_tcp_client NAT changed the port

[codermod]

Hi, I changed the address in the example I know static address server hardsite. The server requires a connection on port 59000.

But using tcpdump on the router I see that the ip is the same but the port has changed at 53000 or 530001 even if I install port 2000 still on the router becomes 53000

When I put 192.168.0.8 this is my second computer on a home network with Ubuntu 14 on it run the simplest server on the sys/socket.h then the example successfully connects takes bytes of my server and sends it all clearly visible in Wireshark on Ubuntu Windows10 Home VertualBox 5.2.12 Gentoo dpdk 17.11 ans FOR 17.11 Network bridge configure VertualBox My router has static IP root access. The exact same problem and 18.11 is installed but there mangled code that does not disassemble.

my action ./ans –c 0x2 –n 1 –base-virtaddr-0x2aaa2aa0000 -- -p 0x1 --config=”(0,0,1)” –enable-kni –enableipsync I see a lot of text …. Checing link status …… done ……. In another terminal ./anscli ip addr add 192.168.0.5/24 dev veth0 (I enter this term in both cases for connection with the computer in a home network and for attempts to connect with the server on the Internet, is it correct?) running an example to stretch over at terminal with ./ans.... User8: lcore[1] Get route failed based on dest IP (0x9999999…) As an example dpdk_tcp_client to connect to the server on the Internet and not local network?

Don't understand your issue. Please list the steps in detail and share your commands.

Sorry My steps ./ans –c 0x2 –n 1 –base-virtaddr-0x2aaa2aa0000 -- -p 0x1 --config=”(0,0,1)” –enable-kni –enableipsync

================================================================= in wireshark on a router in tcpdump I see that the port with 59000 was replaced with 53001. any port I specify in dpdk_tcp_client will be replaced with 53001 but in a local network such doesn't occur, I specified different ports and they didn't change

[bluenet13]

I think you shall configure a default route for external Internet address(0x999999).

[codermod]

to do this, I can either use anscli? or I can overcome a problem only with settings in the Router?

[bluenet13]

You can use anscli to configure the default route in ans. ans> ip route add 0.0.0.0/0 via x.x.x.x

no feedback, close it.
