Placing DirPort at 80 in FreeBSD gives the following warnings - I think because there is a binding issue on ports below 1024:
Jan 06 23:15:40.000 [notice] Opening Directory listener on 0.0.0.0:80
Jan 06 23:15:40.000 [warn] Could not bind to 0.0.0.0:80: Permission denied

So yes probably best to redirect all TCP traffic on Port 80 to Port 9030, otherwise no one browsing the relay address ever sees the exit notice like on most other relays.
