I know i may sound stupid but still.... How is a leased line of 2 Mbps sufficient for an ethernet connection of 100 Mbps, which is behind it? I mean, how come data coming from an ethernet connection of 100Mbps is able to go out through a leased line of only 2Mbps. Even, if the link is getting used to mere 10% of its capacity i.e 10Mbps, how's 2Mbps link sufficient for it?
I believe what you are refering to is a bottleneck. Yes, even at only 2% utilization, the 100meg interface will overload the leased line interface. The 2 meg pipe might be sufficient depending on the number of users behind the PIX, and applications you will use. The PIX will support a larger outside interfaces if you need it.
I've read the other responses, but had the feeling that this is a more general question that you're asking.
A kind of answer is that, how much of that 100Mbps do you actually want to go over the leased line: not a lot - most of the LAN traffic will be local, sent between hosts on the LAN & not sent over the WAN connection. If this isn't the case then either the LAN design needs to be improved or you'd need to assess what your WAN bandwidth requirements are.
The answer to your question then would be in the LAN/WAN design.
Apologies if I've misunderstood the meaning of the question.
The typical 80/20 rules is simply that on average 80% of your traffic will be local LAN and 20% will be WAN (Internet, connection to other site). This is just a rule of thumb and can vary greatly. Anything from all of the servers at one site to a company who downloads streaming media would be far off the mark from this rule but it is a good starting point. Your 2Mbps leased line may be fine for that site if the only thing running over it is your Internet.
