I was exploring the IKEv2 StrongSwan client implementation for Android. What I fail to understand is that Android and Java do not support raw sockets, whilst the IKEv2/IPSec works below the transport layer, which seems counter-intuitive.How exactly does the communication happen after the CHILD_SA aka IPSec SA is established?.

A raw socket is a type of socket that allows access to the underlying transport provider. This topic focuses only on raw sockets and the IPv4 and IPv6 protocols. This is because most other protocols with the exception of ATM do not support raw sockets. VRF-awareness, which enables the router to send Raw Socket Transport traffic to a server host connected through a Virtual Private Network (VPN) Virtual Routing and Forwarding (VRF) interface. This section includes the following topics: "Nmap only supports ethernet interfaces (including most 802.11 wireless cards and many VPN clients) for raw packet scans. Unless you use the -sT -Pn options, RAS connections (such as PPP dialups) and certain VPN clients are not supported. This support was dropped when Microsoft removed raw TCP/IP socket support in Windows XP SP2. Raw sockets allow new IPv4 protocols to be implemented in user space. A raw socket receives or sends the raw datagram not including link level headers. The IPv4 layer generates an IP header when sending a packet unless the IP_HDRINCL socket option is enabled on the socket. When it is enabled, the packet must contain an IP header. Apr 12, 2017 · The Raw Socket client initiates a TCP connection with the Raw Socket server and sends the packetized data across the IP network to the Raw Socket server, which retrieves the serial data from the packets and sends it to the serial interface, and on to the utility management system.
