I just updated to v1.25.0, set CalAmp Port to 5082 and it works perfectly 
root@cloudron:~# ss -ln |grep 5082
udp UNCONN 0 0 0.0.0.0:5082 0.0.0.0:*
udp UNCONN 0 0 [::]:5082 [::]:*
Thanks a lot for your quick help.
Hey @james, thanks a lot for your quick help! Unfortunately port 5082 is exposed for TCP but not for UDP:
root@cloudron:~# sudo docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
7a593b43c164 cloudron/org.traccar.cloudronapp:202603082047210000 "/app/pkg/start.sh" 36 minutes ago Up 36 minutes 0.0.0.0:5082->5082/tcp, [::]:5082->5082/tcp 59d087c4-3c2c-4415-a93e-1d729f90b2ce
As you can see in the previous post, my CalAmp device isn't TCP capable.
I'm running Traccar via Cloudron and trying to connect a ThinxNet LMU30G600.
The CalAmp protocol uses port 5082 over UDP, so the device packets don't reach Traccar.
root@cloudron:~# tcpdump -v port 5082
17:31:47.780025 IP (tos 0x0, ttl 112, id 3, offset 0, flags [none], proto UDP (17), length 217)
lte-out-ml01.sipgatewireless.de.20510 > my.<cloudrondomain>.5082: UDP, length 189
I tried to enable TCP by !RP,2321,1,0, but the tracker responded with ERROR.
Is it possible to also expose port 5082 as UDP by configuration?
