Hello,
I am new to the list, so forgive me if this is a bit naieve, but
qualitatively, what are the system requirements of the bridging
software? I'm hoping to build a transparent bridge/firewall that can
handle about 600kbit/s (~100 packets/s) on a 486dx2-66 (16Meg RAM). Do
you guys think that is realistic or will I run into the same problems?
Thanks.
