I need help with our network configuration. We have an office with about 70 users and 4 servers. Our current configuration is this: T1 > Cisco 1800 > Sonicwall 3060 Firewall > Netgear 24port GB switch. The switch goes out to several other switches throughout the office.
We seem to have some bottlenecking out to the internet. My guess is the bottlenecking is occurring on the switch behind the firewall. We are thinking of upgrading to a Cisco 2960G (48 ports all gigabit). Is this overkill or is our configuration not optimal?
