Direct Connection vs Relay Connection

[swallservices]

I have ports opened and passed through on both sides however I still get a relay connection. Unchecking the box allowing relay connections makes the systems never connect. Using predefined hosts does work so I can confirm the ports are opened correctly.

I'm trying to figure out what I can do to allow a direct connection "the correct way" without using this setting. Any ideas?

Thanks!

..both sides of what - the same LAN? ..or are your devices on different subnets/LANs? ..in which case, this may be why they are unable to establish direct connections!

Can you successfully directly "ping" your devices from each other?

Please also be aware that btsync works with UDP and not with TCP, so check your firewall/NAT settings if it allows UDP or only TCP.

Not strictly true - if your devices are on the same LAN, you can set the advanced setting "lan_use_tcp" to "true" to use TCP instead of UDP

Of course you are right, strictly speaking. As the fallback is to a relay connection, I inferred WAN usage and not LAN usage, but you could of course be right.
