Dear friends,

Are there any ALG (Application = Layer=20 Gateway) modules written by FreeBSD/Linux's divert socket = interface?=20 I found only natd.c used divert socket. As for ALGs for those = protocols=20 which embed connection socket pair information in control channels (eg. = FTP,=20 RealAudio, Quake I,...), it seems most of them are written with protocol = stack=20 callback function interface.

I think ALGs written by = divert socket=20 should be quite portable between operating systems with divert = socket=20 capability, that is why I am looking for such kind of = support.

Thanks.

Regards,

David
