SaaS-based infrastructure and application performance monitoring, tracing, and custom metrics for hybrid and cloud-custom applications. IMHO there is a problem with routing rules but I could not find out how to modify it.Deliver unified and comprehensive visibility for cloud-native, custom web applications to help ensure optimal service levels and user satisfaction with key business services My program writes back packet to tun0 and tshark sees it (in above snippet)īut the ICMP request does not reach eth0 so it could find its way to 4.2.2.4. For example when I execute a ping: ping 4.2.2.4 Written back packet, does not find its route back to go for example to eth0 or to the application layer. My program, writes back the packet without any change back to tun0 device.Now my program starts to read packets successfully (And prints/logs its content). It allocates and instantiates TUN device and waits encrypt its payload) and write manipulated packet back to the TUN interface. write the packet without any change back to the same TUN interface. On a machine with only 1 NIC (eth0) which is connected to Internet, I have written an application which reads IP packets from TUN interface then it may: Packets which are read from a TUN interface, do not find their way when they are written back to the same TUN interface.
