Only connecting via relay


(Ben) #1

I’ve recently installed Manjaro and am trying to get syncthing running, but am finding that it’s always connecting via a relay instead of locally. I have multiple other machines on the network (debian-base, android or windows) which are able to connect locally.

I’ve added syncthing exceptions to ufw, and disabled ufw. It’s still always connecting via a relay (and hence getting terrible speeds).

Log output (some local info abbridged):

Can anyone help?

Multicast and broadcasts need to be enabled on the network for local discovery to work, and the devices need to be on the same subnet.


(Ben) #3

Thank you for your reply. Devices are all on the same subnet (192.168.11.0/24), all except the server being assigned by the same DHCP server. As far as I can tell multicast and broadcast are enabled

You can run with STTRACE=discover,connections and see what addresses syncthing discovers and what addresses it tries to connect to. If it doesn’t discover any local addresses, then multicasts/broadcasts are not working or they are in different subnets.


(Ben) #5

Thank you for your help.

I don’t think it was a multicast/broadcast issue, but the debug logs did help. Experimenting further I found that it could do a local link Manjaro <-> Mint as well as Mint <-> Server, just not Manjaro <-> Server.

The change that finally made it do a local connection was moving the server docker container to it’s own MacVLAN IP address instead of Bridge, but before I got there I also enabled IPv6 on the server and changed the server firewall port from 21027 to 21025, which probably helped too.

I’m still getting rubbish speeds Manjaro <-> Server, but at least I now know it’s not caused by going through a relay.
