All company PCs in the company is physically hook onto a single switch and I was facing IP shortages and I read of MS Win2k3 able to do supernetting. Somehow, I couldn't get much info on how it can be physically implemented. Current network address is using 192.168.9.X with subnet 255.255.255.0. The gateway device is a single port ciso pix firewall configured at 192.168.9.253. The win2k3 server is residing in fixed IP 192.168.9.88. The DHCP server is configured at the Win2k3 server. Anyone can help me out on this? Thanks.
