No NMEA UDP input in openplotter/kplex

[seaspray]

In openplotter I have tried :
[udp]
name = anker
direction = in
optional = yes
address = 10.10.10.1  – 0.0.0.0  – 162.168.178. 52 and 60 240 – 255

Perhaps you need to specify a port (in case you are already using the nmea-0183 default of 10110.
so try

Code:

[udp]
name = anker
direction = in
optional = yes
port = 10120

There's no need to specify an address at this point.  You should also ensure that your networking is correct by opening a terminal shell and typing

Code:

ping 192.168.178.60

or whatever the openplotter IP is and checking that you see valid responses with no dropped packets.
I would also consider using static IP addresses rather than DHCP for any receivers ...
