Hello,
I am new to the list as of today. I work for a small ISP in Michigan, we
have 2 T1's out to different providers in which we run BGP on a Cisco 3640.
My question is this: We are looking for a way to filter traffic (if needed,
due to an attack or similar) inbound or outbound to our network. I believe I
could do this with a dual nic configuration on a FreeBSD machine with ipfw.
Would the machine be able to handle the traffic? and if so, what kind of
specs would you reccomend for a machine to do 3mb/s of bandwidth? We have a
DS3 coming in the soon months, would the machine be able to handle even
that? Here is a diagram (in my great ascii skills.. :/)
2 T1's ----------->Cisco 3640 -------->FreeBSD ipfw box -------->Cisco
3500XL Switch ------>rest of network(dialupandothers)
Is this feasuble(sp)? Would appreciate any comments or reccomendations on
this topic.
TIA,
Brian S. DuRoss
