Ok, I now have the system working. Instead of manually configuring the ip address I set it to dhcp. It went straight through the configuration with no problem and after the install was complete, I then manually configured the IP address as statically. Everything is now fine and dandy. Really don't know what the problem was as the address information I used initially was the same as the one I used post config.
Anyway, never look a gift horse in the mouth as they say.
Thanks for the response, now I just have to crack on with the firewall.
