About:
Ptunnel is a utility that forwards TCP connections over ICMP echo request and reply packets. It allows users to bypass firewalls that block standard TCP/UDP ports by tunneling traffic through ICMP, which is often permitted. This provides a stealthy method for accessing remote services when other protocols are restricted.
Key Features:
  • Tunnels TCP connections over ICMP
  • Bypasses restrictive firewalls
  • Stealthy communication channel
  • Supports client and relay modes
Use Cases:
  • Accessing blocked services on restricted networks
  • Creating covert communication channels
  • Bypassing corporate firewall policies
Alternatives:
  • iodine – Tunnels IPv4 over DNS, better for networks with DNS access but no ICMP
  • ssh – Standard encrypted tunneling but uses TCP which may be blocked
