Ok. This should mean that getsockname() returns the real destination address of the intercepted connection. > I might be wrong, but I think one should compare the address > of an accepted socket to the address of the listening socket. Only works when the listening socket is explicitly bound to a specific address. Quite often it's a "any" socket bound to the wildcard address "0.0.0.0". Regards Henrik
