We're getting a new T3 connection and a Cisco 3845 router with a HWIC-4ESW (4-port switch module).
Would it be possible to simply plug in 3-4 devices into the 4-port switch and assign them public IPs that we get from our provider?
We do something similar already. We have a 2811 with a T1 connection. The 2811 has two built-in ethernet ports. I plugged in one server on one port and other server on the other port. Both have public IPs and everything works great.
Would having the 4-port switch on the 3845 just give me additional ports to plug in more devices?
