Issue with ip aliases and routing

["Jon-david Geier" <jdgeier@xxxxxxxxx>]

I need to get this working. I have a single interface eth0 with a
primary adress of x.x.214.162 on a /30 block network. This interface is
properly set up and works fine, however, I also have five aliased
adresses on the same interface: eth0:1 @ x.x.6.230, eth0:2 @ x.x.6.235,
eth0:3 @ x.x.6.240, eth0:4 @ x.x.6.245, and eth0:5 @ x.x.6.250. All of
these adresses are on a /27 block network. After setting these adresses
up I tested that they were functional ( at least to the local machine )
by pinging each adress all of which responded from the local machine.
The next thing I did was I set a route statement to set the primary (
x.x.214.162 ) as the gateway for the x.x.6.224 network via this
statement: route add -net x.x.6.224 netmask 255.255.255.224 gw
x.x.214.162. I thought this was all I needed in order to be able to
access the aliased adresses externaly from the machine. Unfortunatley
this is not the case. I have ensured that ip forwarding is enabled and
that the adresses are setup correctly. I have also atempted to use the
same route statment with iproute2 via : ip route add 38.98.6.224/27 dev
eth0  proto kernel  scope link  src 38.99.214.162 and I
am still unable to access the adresses externaly from the machine. I
have even brought down iptables to test that there is no conflict
there. Here are the configuration files.

I'm pretty sure that I'm missing just some small detail but for some
reason it evades my notice. Any assitance you can provide me with would
be grately appreciated. Thank you for your time.
