quincytynes Posted November 3, 2014 Report Share Posted November 3, 2014 (edited) Hello, I have a working setup at home where 2 laptops connect through a switch would sync the files without connecting to the internet. edit : I know they synced locally because they where getting speeds of up to 20mb/s which my internet feed won't reach. I do however suspect they connected to the internet to find each other because at my corporate network I am behind multiple firewalls with IPS / IDS and all sorts of smart filters. Now they can't find each other even when they are in the same subnet with no firewalls in between them. Is there any way to let them find each other without using a tracker of some sort ?

RomanZ Posted November 3, 2014 Report Share Posted November 3, 2014 @quincytynesYep. They use multicast 239.192.0.0 over port 3838 to find each other in LAN. Make sure your local firewalls allow it. If it allows - please check if they will manage to connect if you connect at least one of laptops in LAN to wired network. Quote Link to comment Share on other sites More sharing options...
quincytynes Posted November 3, 2014 Author Report Share Posted November 3, 2014 (edited) I will try an isolated configuration tomortow (plain switch nothing in between) to see if it works. Maybe the corporate access points are blocking multicast. I am also building a proxy to help with this problem but it would be nice if local lan sync works.

RomanZ Posted November 4, 2014 Report Share Posted November 4, 2014 @quincytynesAlternative way is defining a "predefined hosts" so your peers won't need a LAN discovery mechanism at all. Though, it requires static IP or DNS name to be available. Quote Link to comment Share on other sites More sharing options...
