Back in the old days of the 2600 and 3600 routers, one could buy 1, 2\nor 4 port ethernet modules with true routing capability. The latest\nrouters from Cisco dont seem to support this kind of function. I have\nan 1841 which comes with two 10/100 ports on board. I want to add two\nmore ethernet ports to make it a full 4 port router. But i cant find a\nsuitable module. Cisco do a 4 port etherswitch HWIC. But this isnt\nlayer 3 capable. Any suggestions?
