It sounds like you have two security managment domains, correct?
(I.e. "yours" and "corporate") The most
straighforward aproach would be to have the corporate VPN device
permit/deny traffic to your servers based on the user Id they logged in
with. Without knowing the type of access you're wanting to limit,
I'll have to guess at some answers.<br/>
<br/>
If the servers are UNIX, you could issue SSH keys to the people you want
on, then open that port up to the corporate VPN DHCP range.<br/>
<br/>
If the servers are Windows, you might have to investigate the domain
security options and permit/deny people based on their login credentials
too.<br/>
<br/>
If the type of connection is a client-server application based on a
programs specific protocol, then you'll have to investigate an application
layer proxy or security mechanism within the server application
itself.<br/>
