I am having two different networks connected to the same SWITCH D-Link DES-1024D.
This network is VPN through Sify (ISP) to connect to remote server. This network doesn't have internet.
This network is using Microsoft ISA (Internet Security & Acceleration Server) server installed on Windows 2000 server, for internet sharing purpose. Basically this is internet group.
ISA server is having 2 NIC cards. One Nic is having Cable modem Static IP, and internal NIC is also having static IP (192.168.0.1).
Clients default gateway is 192.168.0.1.
Both the groups are working fine. But when I want to transfer files from first group to other group, it is difficult to me. Presently I am changing the IP to that group and getting the things.
But what I want is to do is, share the files and printers just as they are in same group. But I don't want to give internet to the first group except microsoft.com and Antivirus site to update Window & antivirus dat files automatically. And my VPN connectivity should not expose to public.
Here I am attaching the diagram for better understanding.
If anyone can help in this regd, would be greatful.
