I am in a bottleneck concerning design. Basically, I have generic switch connecting my LAN together. I want to provide wireless connectivity to couple Windows 2003 member servers. So I bought a Linksys Router/Access Point/Switch. The problem is where to place it effectively. Should I connect it to my ISA firewall on the 3rd network card? or behind the DSL modem? I was thinking just plugging it to a port on the switch to ease configuration hasless since the only PCs I want to give wireless connectivity are managed member servers.
I know that if I want to provide wireless access to unmanaged computers and/or users with lets say laptops and else, it is best practice to connect the access point to a wireless DMZ interface on the ISA firewall, however it is long configuration and is not the case.
If I place the Linksys behind the modem then my ISA firewall wont have the public IP address assigned to the external interface which I use for external VPN and I really want to avoid doing this.
