From tcpdump on de1 I see that a ping for 205.219.89.42 (pimin) ends up at 
205.219.89.41 (rtr).  205.219.89.41 then asks "who has pimin tell rtr" 

I tried to do "arp -s pimin ..... pub" and get the error message:

  set: proxy entry exists for non 802 device

I don't know how to get pimin proxied?  What should I do?

I have nat set for:

map de1 172.16.89.42/32 -> 205.219.89.42/32 
map de1 172.16.89.43/32 -> 205.219.89.43/32
map de1 172.16.89.44/32 -> 205.219.89.44/32

Sorry if I'm amazingly stupid about this.

TIA,
Paul

Router box is compiled with option GATEWAY and when I run:

   /usr/sbin/sysctl -w net.inet.ip.forwarding

I get:
