I just changed from a networking HUB to a LINKSYS ETHERFAST Workgroup Switch. However, I cannot get my workstations to talk to the router/firewall. I also cannot ping the workstations from the router/firewall. I am trying to run DHCP, but cannot tell if that is working either since none of the systems are talking to one another. I am running straight through cabling, but not sure if I need to run a cross over from the router/firewall to the switch. Currently running Red Hat 7.1 Kernel 2.4.9-31 with MonMotha Firewall script 2.3.7.
Your help is greatly appreciated. Jason
