I've got PPP over UDP > going now Something you should be aware of about the current PPPoUDP implementation - it's possible for an attacker to insert arbitrary packets into your data stream (targeted at the ppp -direct side) as PPPoUDP doesn't insist on the peer address (recvfrom() sockaddr) staying the same. This is usually a bad thing. I've been discussing the writing of a UDP multiplexor with Mark Knight (cc'd) that can maintain multiple udp sessions in much the same way as you *might* want inetd to handle sessions.
