[UK-CONTEST] N1MM and IPv6

[Chris G3SJJ]

Thanks Stewart. That is just the setup I was trying to achieve! We have used a Cat 5 ethernet cable between two laptops without a Cluster connection 
successfully for several years but last year we had a WiFi connection available. We found there was a conflict and could have PC to PC network or 
Cluster but not both. This is why I was trying to go via the home BT Router for now to establish what was and wasn't feasible!

Thanks also Adrian. I have gone back to the Cat 5 setup for now but I no longer have radio Cluster system. I had to use 2m in the early days of 
Cluster but have never ben interested in anything to do with VHF!

Also , also! Thanks to Robert M0VFC who is working with me to try and resolve the weird IP addresses on the Samsung Windows 7 laptop. What is puzzling 
us is that the IPv4 address which would normally be assigned automatically as a 192. etc address shows a Public IP address, which is why I suspected 
it was using IPv6.

That didn't work and *would* require a router; the local networking got screwed up and the master network number would be reported as 17 which indicates that machine couldn't be found in the network table (and Qs made on that machine are therefore beyond the reach of editing etc). According to N2IC one of the N1MM coders, N1MM networking is not designed to be used with more than one network interface on any pc, and that was the problem. Solution is to use a router.
