Abstract
Linux's NAT (Network Address Translator) implementation, IP Masquerade, includes a VPN Masquerade feature that provides interoperation of NAT with IKE and ESP tunnel mode within the IPSec security protocol suite. VPN Masquerade uses heuristics to route packets from a server on the Internet to a client on a local network that shares access to the Internet with other clients over a common access link through a router running NAT. VPN Masquerade, however, is susceptible to crashes, collisions and race conditions that can disable IPSec communication. These are prevented, or recovery from such is automatically effected, by sending over a tunnel a control packet, a 'ping', from the client at one end of the tunnel to the server at the other end of the tunnel, and then waiting to send any packets other than a control packet over the tunnel until a responsive control packet is received from the server.
