pick a udp port being hit. e.g., 56846 Place a sniffer on the port:

tcpdump -i eth1 -vnn -s0 -X port 56846 -w port56846
tcpdump -nn -v -s0 -X -r port56846 |less

collect the addresses from the logs:

awk -F '[ =]' '/56846/ {print $14}' /var/log/messages >>athena-udp-src

awk 'BEGIN { FS="[ =]" } /DPT=17500/ && /^Jun 21/ {print $14}' /var/log/messages |sort -n |uniq |while read line; do echo -n $line " "; host $line ;done
Be sure to change the date from Jun 21 to your desired date
