I am assisting a local charitable organization with a clean-up and refresh of their network and cabling mess. They have a Sonicwall TZ190 for the Office network and a Sonicwall TZ210 for their Guest network. Feeding into the Sonicwalls are the outputs from two cable modems on a cable splitter broadband drop from Charter. The existing network used H-P Procurve Layer 3 switches and we will be replacing those with donated Layer 2 Cisco 3560's. The current set-up has two VLANs and the Procurve's are tagged accordingly. I want to remove the VLANs and just run two separate networks on the new switches with (hopefully) no VLANs. The one hitch is that the office manager needs to access the Guest server from her Office workstation. Therefore, there must be an Interface to Interface link between the two Sonicwalls. From everything I have read, this should be possible. The Office subnet is 10.0.0.x and the Guest is 192.168.200.x
Can somebody really familiar with the Sonicwalls provide help with this relatively simple design? Am I correct in assuming that there is no need for VLANs here? Thank you in advance!
