Hello all. I just finished putting a iptables firewall together and keep getting this log about every minute or so. It is comming from my router on UDP port 520. From what I understand UDP port 520 is used for local routing processes. Should I continue to block this traffic or allow it. If I do allow it, what are the security conserns involved? Thanks.
