I have a closed caption system that will send out captions over a IP and UDP port to a single location but I would lke to multiplex it to other locations. right now I have the caption hardware sending it to my Ubuntu server on port 10010 but I would like to send this along to a secondary address off network .

currently I grab it using
socat -lf /dev/null udp4-listen:10010,reuseaddr,fork stdout >> captions.txt

​

so... my question is how can I take the incoming packets and record them to a text file and than send them out of my ubuntu server to a another network solution on the same or different port?
