Dear all: I have the following problem: I would like to send an IPv6 packet using a given interface, to the address that corresponds to another interface of the same machine. This, that seems a bit akward, it would be interesting for obtaining accurate packet latency results to test other systems that could be placed between the two interfaces (routers, etc.). Since the sending and the receiving process share the same physical clock, microsecond precision could be obtained in the measures. The problem is that FreeBSD recognises that the destination address is in the same machine, and routes directly through the loopback interface, without sending actually the packets through the wire. Anyone knows a trick to do this? -- ********************************* Juan F.
