Our desire would be more to be able to assign IPs from our > address space to roaming users. I had looked into this at the past, and read the relavent RFCs and MS documentation on it. It is a bad joke, all the way arround. First it uses a modified version of the GRE protocol (that is why I asked about GRE support in the kernel way back when), as an encapsulation around the PPP packets. It also must have a TCP connection between the client and the server to act as a controll connection. If that control connection is lost for whatever reason , the tunel is closed. Oh yes, one last thing, the GRE portion of the tunel, where the data actually goes, has an ack/nak, sliding window and retransmit system (again, outlined in the MS documentation). While I think this would be a good thing to have, just to be compatible, and ideally as a part of a larger 'iptunel' packagel; it is *alot* of work. -- David Cross To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
