Assigning VPN IPs - 13.Feb.2008 11:39:42 AM

We have an enterprise array which was originally put in place to serve OWA traffic, but is now being reconfigured to also support an L2TP/IPSEC remote access vpn solution.

Due to its original purpose, the internal nics were placed on a subnet with a /26 subnet address - This strictly limits the number of internal IP addresses we can allocate to incoming VPN clients.

Our network guys tell us that if our incoming VPN was configured to use NAT OVERLOAD then we could grant access based on a single internal address, and would therefore not need to readdress the internal nics to provide a larger number of available addresses.

Does ISA (2004) support this functionality? Does the above even make logical sense? - i'm a server guy not a networks guy.

Thanks in advance
