- How much traffic is on you existing net. segments? If it is alot then the
- additional nics will help. But!!!!!!
-
- the server will not route IP!!!!!!!!!!!! <===I don't know if you can install
- the MPR nlms to make 3.11 an IP
- router though? Kinda expensive.
-
- a cheaper way would be to do this and install the additional nics into the
- server as needed and add KarlBridge(from OSU) to just let IP protocols pass
- thru onto the network segments(I assume they are ether). You'd need a couple
- of free ATs and ethernet cards.
