I don't think this sent so I am trying again.  Sorry if it is a dupe.

In FreeBSD 
# ping -I fxp0 208.67.222.222
ping: invalid multicast interface: `fxp0'
# ping -I fxp1 208.67.222.222
ping: invalid multicast interface: `fxp1'


http://www.freebsd.org/cgi/man.cgi?query=ping&sektion=8&apropos=0&manpath=Fr
eeBSD+4.3-RELEASE
  -I iface
Source multicast packets with the given interface address. This
flag only applies if the ping destination is a multicast address.

traceroute -i fxp0 -I 208.67.222.222
traceroute -i fxp1 -I 208.67.222.222

Both work

ping -S 192.168.2.1 208.67.222.222
works but I have a hunch that it just sends through the WAN interface with
that IP.  If that makes any sense.
