I have attached a pdf file of our current network diagram and a proposed network upgrade layout. We currently have a site with less than 50 workstations, a few servers and networked printers that are all hanging off of 2950T switches and all on the same /24 network. I would like to add a 48 port 3560G for the core switch, move the existing 24 port 2950T at the core to a "dirty switch" outside the firewall and add a 2811 router to setup a few vlans to start organizing the network better. I have a config I can use for reference for the ACL's and VLAN setup. We would probably only need 6-7 VLANs to start with. Are there any problems with this layout?
