I have a client who is setting up a serviced office complex. He wants to be able to share an ADSL line between himself and his clients but does not want the clients to be able to see anything on the company's network like exchange servers, files servers etc. The ISA currently has three network cards installed, WAN, LAN1 & LAN2. WAN is connected to a D-Link DSL Modem & a 2Mb ADSL with multiple static IPs (4 i think), only 1 is assigned to the WAN interface. LAN1 is assigned 192.168.0.2 and currently has all users connected. LAN2 is assigned 192.168.0.3 and is currently inactive. If I move all the clients onto this interface will they be able to access the internet but not the machines on LAN1? Can anyone think of a better solution? Thanks Matthew Bunce Kluster (UK) Limited
