OK
I have added the following to the rc.local :-
ifconfig_fxp0_alias0="inet 195.224.237.17 netmask 255.225.255.255"
And have run the command from the command line
netstat -nr gives :-
Internet:

And ifconfig fxp0 gives :-
root@neophile:/etc >ifconfig fxp0
fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet6 fe80::208:c7ff:fecb:ef97%fxp0 prefixlen 64 scopeid 0x1

ether 00:08:c7:cb:ef:97
media: autoselect (100baseTX) status: active
It seems to me that the broadcast address on .17 may be wrong
Also pinging the IP from the same box gives :-
PING 195.224.237.17 (195.224.237.17): 56 data bytes
ping: sendto: Can't assign requested address
ping: sendto: Can't assign requested address

I have also gone through the discussion at:-
http://www.stl-group.com/4.0/library/kbase/os/5.shtml
which describes exactly what I want to do.
I must be missing something here - But damned if I can figure out what :)
