I have one Windows 2003 server with two NICs, one on the internal Lan the the other to run our Public Wireless Network.
On our internal LAN the IP is 192.168.10.#. That Lan can access the Internet through its own gateway.
I have a virtual server running on the same server using a NIC with an IP of 192.168.103.#. It also can access the Internet through its own gateway.
Previously, I had the wireless running on a seperate Linux Box and I could NOT access the internal LAN. Unfortunately, since I moved that to the Windows server I can access the Internal Lan using Remote Desktops etc...
I do have a 5510 ASA device that both networks go through.
How can I block the wireless network from accessing the internal lan? I do need the internal Lan to be able to access the wireless Lan (Which it now can do).
After I installed the virtual server and connected it to the wireless Vlan. Next I got a laptop and signed on to the wireless network, just like the public would.
I started testing to make sure the two networks were isolated.
Specifically I tried to RDP into the secure server and I could RDP in. That is when I knew I had a problem, we don't want the public able to access out internal network.
I disconnected the wireless Vlan and powered up the stand alone server I was using, I could not RDP into the internal network. At that point I suspected something about the same server having 2 Nics on different networks must be the problem.
