Wow, that's a BIG subnet!  :-)

I'm betting your problem has to do with host name resolution.

If your servers are behind your firewall, the private IP's don't 
match up with the public IP's your server names resolve to.

But, I'd need a lot more details than you supplied, to be sure.

If that's the case, I run my own internal DNS servers at work to
get around that problem.  You _may_ also be able to handle it in
/etc/hosts .
