*thinking out loud hypothetical situation* If you were connecting to a sync that relied on manual IP relays and you tried to sync on Android/iOS (and you were on an IP that was whitelisted) would it work? Or do the mobile apps exclusively use DHT and UPNP?

To make this a whole lot easier just use this: http://www.ipaddresslocation.org/ip-address-ranges.php I tested it out with a IP block I own and it seemed to work fine. Just put 192.168.1.1/24 (for instance) and it will spit out a list of all the IPs. Copy that and either use a script that will add the ports to the end or enter them by hand and then just paste that list to all your VMs. I'm in a similar boat to you (as far as your goal to have a custom tracker/relay), but at the moment this seems like the best way to go about it. For the time being it might actually be more secure this way because all the nodes will only be able to connect to the specified IPs (of course that is if they are all accessable to eachother as GreatMarko mentioned.

I would even suggest just going with FreeNAS on a USB stick and then loading up BTSync (freebsd version) on the ZFS pool you make, it's what I use personally and it runs fine (as long as you run it from the pool (ei /mnt/yourzfspool/).

Has anyone run BTSync in a colo setup? Meaning that everything is on 1gb or higher among maybe 4-7 servers (or more)? Just want to know what kind of performance people have seen. Thanks
