Re: [Skunkworks] Weird VPN problem between Cisco Routers - RESOLVED

So a JTL engineer took a look and couldn't find a solution. I consulted my local guru and you guys don't want to imagine what the solution was: He looked at the config and all seemed well. He created a new tunnel - named it tunnel51 - with the exact same params as tunnel49 and everything worked perfectly. So the problem, according to our diagnosis, is that the router which was showing 'line protocol is down' had suddenly hated the name 49 and wanted a different name. 51 did it. One day you encounter such a problem, you know what to do.

Good people, does anyone here have experience with the calculation of distance between two nodes connected intermittently via Bluetooth? In my use-case the nodes are in constant motion withing the same area. -- ................................................................................................................................................................. Business, more than any other occupation, is a continual dealing with the future; it is a continual calculation, an instinctive exercise in foresight.
