Hello, I have a 3- homed configuration of ISA (with MZ and DMZ) and I want certain public Ip's from the Internet to have access to PC's and Servers inside my MZ. I want those ip's to pass through ISA and have file access to the servers and pc's inside the MZ not to publish the machines in MZ to certain outside IP's. The machines in MZ have 192.168.10.x ip's. I suppose I have to implement a VPN. Can anyone give me a hint (just a start on were to look to ) for Implementing it or give me some ideas? Thanks
