Paul,
After the VC is established, the first packet over the link is an IP
packet containing source/destination IP addresses and, probably, a TCP
SYN packet or a UDP packet. Won't the Source/Dest address in the
first IP packet be sufficient or have I missed some initialization
problem on the receiving end?
