 ## Port forwarding for TMTC commanding
 
-This requires using the TCP on sender side (Python client) and receiver side (OBSW TMTC TCP server).
+If you are using the UDP communication interface, you can use:
 
 ```sh
 ssh -L 1536:192.168.133.10:7301 eive@2001:7c0:2018:1099:babe:0:e1fe:f1a5 -t /bin/bash
 ```
 
+This forwards UDP TMTC packets on port `1536` of localhost to the TMTC reception port of the Q7S.
+
+For TCP, you can use
+
+```sh
+ssh -L 1537:192.168.133.10:7303 eive@2001:7c0:2018:1099:babe:0:e1fe:f1a5 -t /bin/bash
+```
+
+This forwards TCP TMTC packets on port `1537` of localhost to the TMTC reception port of the Q7S.

 ## Set up all port forwarding at once
 
-You can specify the `-L` option multiple times to set up all port forwarding at once
