I am about to upgrade a network of 20 local clients, 3 laptops and 12 remote Terminal Server users. The upgrade involves migrating (swing migration) from the current SBS server (P4 Spec.... bad) to a new Xeon Dual core with SBS 2K3 on it. I will be bringing in a Cisco 877-WGA-K9 Integrated Services Router with Wireless into this environment, It is a 2 Nic setup as follows:
255.0.0.0 SN | 255.255.255.0 SN
Cisco 877 -------- SBS 2003 DC ---------------24p Switch-------------Clients
| Terminal Server
I guess i have several questions
1: Currently ISA is not installed and am wondering whether the Cisco 877 will be sufficient security wise?
2: I will use the Cisco security software for connecting wireless clients to the router, what options do i have for connecting to my intranet? VPN? do i need ISA?
3: What main issues will i encounter with this set up and what steps can i take to avoid them?
I believe ISA was on there in the past and they (hopefully) have backups of settings etc so it is an option to put it back on. I will be migrating the settings off their current server to a new one using Swing Migration and so would like to get everything perfect for when the upgrade is complete.
