well here is what it got this time: DNS request timed out. timeout was 2 seconds. *** Can't find server name for address 192.168.0.200: Timed out *** Default servers are not available Server: UnKnown Address: 192.168.0.200

This is still nslookup - the timeout/error should not happen in normal dns resolution.
How can i fix the revrese resolving issue?
Number to name resolution is exactly the same as name to number, except that the actual names involved are constructed by reversing the IP number octets and appending in-addr.arpa. If your server isn't configured to answer for your private address ranges itself, it will pass the query off to the root servers like everything else, and of course no one else is going to know anything about your private ranges.
If you look at the entry for zone 0.0.127.in-addr.arpa noting that the filename must be different for each zone and lives in the directory mentioned at the top (relative to the chroot location if your version does a chroot), you will see what you need to do. If you have webmin, it will offer to build the reverse zones for machines you put in forward lookup zones but you can do it by hand or find a script that does it if you prefer. To fix your nslookup issue you only have to make 192.168.0.200 work, so try adding that to understand the principle.
*super dns newb here. How would i go about making it work? i'll take a gander inside webmin and see if i can figure it out though*
Also, you mentioned earlier that you wanted to use another server as the forwarder. Does that one already have entries for your private IP's?
*No it does not. The firewall is basiclaly jsut a forwarding nameserver and AFAIK does little if no caching.*
I've always wondered why distributions don't come preconfigured with canned answers for all the RFC 1918 private address space to reduce the nonsense queries to the root servers.
