Yes, Yes you can. However, wireshark may use a lot of hard-drive space if you leave it running for a long time (and there is a lot of activity on those ports). See, each time a packet is sent or received wireshark records it... if you set filters, then you can tell it to only record say, UDP traffic, or specific port numbers, or only specific port numbers with UDP traffic, etc. So, you run the program, take the port numbers in question, and tell wireshark to filter out everything except UDP traffic on those specific ports. Then, whenever UDP data is sent or received on those ports.... wireshark will record it. So if these ports send data, say, every three minutes... and you go home, when you come back 8 hours later, you are probably going to have quite a large log file or memory consumption.... if it only sends data once an hour, then you won't have much used at all.
