I'm just getting started for CCNA. I've seen the 851w recommended as a good router that could carry me on to studying for CCNP.
I didn't see any serial interfaces in the specs for this router (but I could have missed it). Is this a big deal? How far could this router take me in my studying?
Also, is it possible to use this router if I set up multiple virtual pc's on my computer or do I really need another computer to attach to the router?
What are some other things I should know about when setting up a lab at home with this particular router?
Thanks in advance.
