SnowLeopard Server not providing Lion clients software updates

Question

Hi everyone,
I've seen countless threads with the same problem and there doesn't seem to be any response whatsoever from Apple on this issue so I'm hoping someone else can shed some light on this issue..
I configured my Snow Leopard Server (10.6.8) to provide Lion client updates on my network as per the instructions and it's just not working!
My Lion clients are currently running 10.7 and I'm looking to get them updated as quickly as possible. If I cant resolve this I'll be putting them back to Snow Leopard - I knew I'd regret installing Lion!
swupd.plist:
<key>otherCatalogs</key>
          <array>
                    <string>index-leopard.merged-1.sucatalog</string>
                    <string>index-leopard-snowleopard.merged-1.sucatalog</string>
                    <string>index-lion-snowleopard-leopard.merged-1.sucatalog</string>
          </array>
     swupd.conf
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{HTTP_USER_AGENT} Darwin/9
    RewriteRule ^/index\.sucatalog$ /index-leopard.merged-1.sucatalog
    RewriteCond %{HTTP_USER_AGENT} Darwin/10
    RewriteRule ^/index\.sucatalog$ /index-leopard-snowleopard.merged-1.sucatalog
    RewriteCond %{HTTP_USER_AGENT} Darwin/11
    RewriteRule ^/index\.sucatalog$ /index-lion-snowleopard-leopard.merged-1.sucatalog
</IfModule>
     Clients:    
mbpro:~ Barry$ defaults read /Library/Preferences/com.apple.SoftwareUpdate CatalogURL
http://sus.domain.com:8088/index-lion-snowleopard-leopard.merged-1.sucatalog
On my clients I am receiving the following:
The Software Update Server (sus.domain.com) is not responding.
Check to make sure your network connection is operating normally. If there are no issues with your connection, contact your network administrator for assistance.
And if I look on Server Admin, searching for "10.7" none of those updates are copied/enabled and I can't see any OS Combo Updates?!? This has been set-up for a few days now and still nothing.
If I try to access the sucatalog url in a browser I receive a 403, forbidden error. If I do the same for say the snowleopard catalog URL I am able to view the catalog.. Permission error somewhere perhaps? Although I'm more inclined to believe that I'm unable to view the contents of this file as there are simply no 10.7 updates in the sus repository.
Oh! and it's worth mentioning that Snow Leopard clients are able to make use of the Software Update Server..
Appreciate any input
Thanks!

Hi,
I'm really sorry but because it was a while back I can't quite remember. I should have posted it in my response above, I hate when people don't do that!
If you need me to check any of my particular config I'd be more than happy to have a look
