.SH PORT FORWARDS
|
||
.sp
|
||
If you have a NAT router which supports UPnP, the easiest way to get a working
|
||
port forward is to make sure UPnP setting is enabled on both Syncthing and the
|
||
router – Syncthing will try to handle the rest. If it succeeds you will see a
|
||
message in the console saying:
|
||
.INDENT 0.0
|
||
.INDENT 3.5
|
||
.sp
|
||
.nf
|
||
.ft C
|
||
Created UPnP port mapping for external port XXXXX on UPnP device YYYYY.
|
||
.ft P
|
||
.fi
|
||
.UNINDENT
|
||
.UNINDENT
|
||
.sp
|
||
If this is not possible or desirable you should set up a port forward for port
|
||
\fB22000/TCP\fP, or the port set in the \fISync Protocol Listen Address\fP setting.
|
||
The external forwarded port and the internal destination port has to be the same
|
||
(i.e. 22000/TCP).
|
||
.sp
|
||
Communication in Syncthing works both ways. Therefore if you set up port
|
||
forwards for one device, other devices will be able to connect to it even when
|
||
they are behind a NAT network or firewall.
|
||
.sp
|
||
In the absence of port forwarding, relaying may work well enough to get
|
||
devices connected and synced, but will perform poorly in comparison to a
|
||
direct connection.
|
||
.SH LOCAL FIREWALL
|
||
.sp
|
||
If your PC has a local firewall, you will need to open the following ports for
|
||
incoming and outgoing traffic:
|
||
.INDENT 0.0
|
||
.IP \(bu 2
|
||
Port \fB22000/TCP\fP (or the actual listening port if you have changed
|
||
the \fISync Protocol Listen Address\fP setting.)
|
||
.IP \(bu 2
|
||
Port \fB21027/UDP\fP (for discovery broadcasts on IPv4 and multicasts on IPv6)
|
||
.UNINDENT
|
||
.SH REMOTE WEB GUI
|
||
.sp
|
||
To be able to access the web GUI from other computers, you need to change the
|
||
\fIGUI Listen Address\fP setting from the default \fB127.0.0.1:8384\fP to
|
||
\fB0.0.0.0:8384\fP\&. You also need to open the port in your local firewall if you
|
||
have one.
|
||
.SS Tunneling via SSH
|
||
.sp
|
||
If you have SSH access to the machine running Syncthing but would rather not
|
||
open the web GUI port to the outside world, you can access it through a SSH
|
||
tunnel instead. You can start a tunnel with a command like the following:
|
||
.INDENT 0.0
|
||
.INDENT 3.5
|
||
.sp
|
||
.nf
|
||
.ft C
|
||
ssh \-L 9999:localhost:8384 machine
|
||
.ft P
|
||
.fi
|
||
.UNINDENT
|
||
.UNINDENT
|
||
.sp
|
||
This will bind to your local port 9999 and forward all connections from there to
|
||
port 8384 on the target machine. This still works even if Syncthing is bound to
|
||
listen on localhost only.
|
||
.SH VIA A PROXY
|
||
.sp
|
||
Syncthing can use a SOCKS5 proxy for outbound connections. Please see proxying\&.
