I did try "noconn" while monitoring with snoop and a Sniffer, and under
2.0.5R (from the CD also), it did not solve the problem of differing
ip_addrs. My traces showed ICMP Destination unreachable (Bad port) with
or without noconn. But, there's no arguing with results. I couldn't get
it to work, and documented it months ago. No sense going back now...
