Transparently tunnel your IP traffic through ICMP echo and reply packets.

'icmptunnel' works by encapsulating your IP traffic in ICMP echo packets and sending them to your own proxy server. The proxy server decapsulates the packet and forwards the IP traffic. The incoming IP packets which are destined for the client are again encapsulated in ICMP reply packets and sent back to the client. The IP traffic is sent in the 'data' field of ICMP packets.

Packet and byte counts on TCP connections
IP, TCP, UDP, ICMP, non-IP, and other packet and byte counts
TCP/UDP counts by ports
Packet counts by packet sizes
Packet and byte counts by IP address
Interface activity
Flag statuses on TCP packets
LAN station statistics
