IP/ICMP network layer | TCP/UDP transport layer - custom realization

Network capabilities:

• Listening for all incoming traffic (Ethernet, ARP, IP, ICMP, TCP, UDP etc)
• Changing IP options (0x14 - 0x3C | + hlen > 5) before sending packets
• Changing Network layer packet as a whole (for example, manual entry source IP and destinaton IP etc)
• Changing Transport layer packet as a whole (for example, manual entry TCP/UDP ports, ICMP type requests etc)
• Is the host alive on the network
• Traceroute with writing IP from output/input interface machine (IP RR & IP TTL respectively)
• Ping

In the future:

• The realization of the opportunity to reach the machine behind NAT ( IP(SR)+ICMP(ECHO_REQ) )
