I am getting ready to replace my 10Base-T switch with a Gigabit model. Several of our newer servers already have 10/100/1000 Mbit network cards but the router/firewall we use is a bit antiquated and still a 100 Mbit model. My question is, will internal network be throttled down to 100 Mbit by the router between servers and clients or does traffic bypass the router once link between client and server is established? If not, would a managed switch offer a solution? Thanks.
