[LARTC] Can't one filter based on a single destination address?

[LARTC] Can't one filter based on a single destination address?

[Andrew]

<PRE>Greetings:

I'm running kernel 2.2.17 and I've been trying to add a rule which looks up
table main based on a single destination address. Here it is:

&gt;<i>ip rule add from 0.0.0.0/0 to 192.168.107.28 lookup main prio 110
</I>

The rule adds fine however it seems that the kernel fails to match the
destination condition. 
Incidentally 192.168.107.28 is the local address of an interface on 
the box where I'm adding the rule. The machine I'm testing from is
on the same physical network and has address 192.168.107.27. I'm using 
ping to test.

With the above rule in place, and a blackhole rule immediately following
it. I can't ping 192.168.107.28 from .27. However if I change the rule 
above to read:

&gt;<i>ip rule add from 0.0.0.0/0 to 192.168.107.0/24 lookup main prio 110
</I>
then I can ping fine. Thinking that I might be required to specify a mask,
I even tried the following version:

&gt;<i>ip rule add from 0.0.0.0/0 to 192.168.107.28/32 lookup main prio 110
</I>

No luck. Does any one know what's going on?
