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:
Destination        Gateway            Flags      Netif Expire
default            195.224.237.1      UGSc       fxp0
127.0.0.1          127.0.0.1          UH          lo0
195.224.237/26     link#1             UC         fxp0 =>
195.224.237.1      0:10:7b:74:5:61    UHLW       fxp0   1195

195.224.237.11     0:40:33:59:cd:49   UHLW       fxp0    191
195.224.237.16     0:a0:24:70:cb:12   UHLW       fxp0    440

195.224.237.63     ff:ff:ff:ff:ff:ff  UHLWb      fxp0

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
        inet 195.224.237.7 netmask 0xffffffc0 broadcast 195.224.237.63
        inet 195.224.237.17 netmask 0xffe1ffff broadcast 195.254.237.17
        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
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 :)

actualy the rc.conf line should look like:
ifconfig_fxp0_alias0="inet xxx.xxx.xxx.xxx netmask 255.255.255.255"

if you want to add yet another alias it would be:
ifconfig_fxp0_alias1="inet xxx.xxx.xxx.xxx netmask 255.255.255.255"

and so on...
