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.
