Hello list! I'm trying to implement port forwarding over LWIP.
One side is Linux x86_64 machine another one is FreeRTOS ARM device. I have LWIP stack on both sides of PPPoS channel, and data transfers ok. tty read/write is fast and stable. On IP level I see that ping example app works well, I can ping opposite side with raw sockets API and it takes about 12ms over PPPoS on 115200 baudrate. However when I start to use TCP level things goes terribly slow. Even simple echo server takes several seconds receive an answer. I use default lwipopts from lwip-contrib/examples/example_app/lwipopts.h, just added PPP_SERVER and PPP_NOTIFY_PHASE support. Here is my log https://pastebin.com/raw/tfwY1rtV And lwipopts.h https://pastebin.com/vd2DrxYJ Can somebody tell me what is wrong with my log/config? -- _________________________________ Best regards, Mednyy Alexey. _______________________________________________ lwip-users mailing list lwip-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/lwip-users
