This is happening because the two endpoints are encrypting/decrypting with different keys (or different algorithms). I know of at least one Mac client that was broken (I think that it was doing 'stateless' mode incorrectly, but don't remember the details). If you can scrounge up a Microsoft PPTP server and try your Mac client against it, that would show whether the Mac client is to blame (assuming the same MPPE options were negotiated). Try also playing with the key length, turning 'stateless' mode on/off, etc. -Archie __________________________________________________________________________ Archie Cobbs * Packet Design * http://www.packetdesign.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
