I'm spec'ing a server for Forefront TMG. We have 4 VLANs, and 2 ISPs. Does that automatically mean I should have 6 NICs? Can I use 1 NIC for ISP redundancy?
I do have L3 switches, but they are absolutely atrocious (Dell 6248) and I'd like to keep as much stress as I can off them to ensure reliability.
The VLANs are:
Management (Servers, management IPs)
Public kiosk PCs
Public (anonymous unsecured) wireless
