I've had a network configured for a customer for the past six months or so. Its a gateway network with the primary gateway PC configured for an IP address of 10.0.0.110 on the local network. When connected via Hamachi the IP address has always stayed 10.0.0.110 on the gateway network as well, but over this past weekend I found that Hamachi was reporting the IP address as 10.0.0.130, while the actualy NIC IP was still 10.0.0.110. I did a little troubleshooting and ended up removing and reinstalling Hamachi several times and each time the Hamachi IP changes by one number so that now its at 10.0.0.136. Any clue as to why this is happening? The customers system relies very much on this address staying static and changes have thrown the whole system into a tailspin. I still dont know why the address changed in the first place.
