- Wed Apr 06, 2016 6:18 pm #45008 netcat uses the following values when it sends to ESP. The netcat source port is a random value generated whenever netcat starts. netcat listens for responses on the source port it sends to the ESP.

Code: Select alldestination ip=<ESP IP addr>, destination port=8888, source ip=<Linux IP addr>, source port=57907

The ESP UDP test uses the following values when it responds with "acknowledge". Note the destination port is the remote/source port.

Code: Select alldestination ip=<Linux IP addr>, destination port=57907, source ip=<ESP IP addr>, source port=8888

Perhaps the terminal program sends to port 8888 and expects responses on port 8888. But it should listen for responses on the source port it sends.
