If you are running 2.1R, go to ftp.freebsd.org and download a file from the -stable branch (I think the path was usr/src/sys/netinet) called in_rmx.c and replace your in_rmx.c with the one from stable. Then remake your kernel and all should be well. You should note that this doesn't keep the arp entries from appearing, but it does allow new connections to overwrite the old routes; it works.
