Setup in Regards to Security

[Guest]

Hello All, I currently have a 10 user network using a front end exchange
server/vpn server and a backend exchange server behind a cisco firewall both
running 2000. Can anyone suggest a better setup or point me to some MS
documentation that might explain a better method.

Thanks in advance.

One other note: The front end exchange/VPN server is also doing NAT.

Thanks again
