Easily. You'll get less latency with a 2.2.5 or higher kernel for Linux in
general (200ms/connection improvement under some circumstances) - this is
most important for Web servers, but applicable to almost anything dealing
with Win* or some BSD clients - NAT may be an exception,
I'm not sure if you're reassembling frags.)
I've just started looking at 2.2.9 as a candidate for deployment, but am not
at the point where I could offer an opinion on a particular 2.2.x
kernel. If you're using RedHat 5.2, you'll need to do the RPM upgrades
necessary for 2.2.x kernels first.
128Kb/s of bandwidth isn't all that much though. I haven't looked
specificly at doing NAT vs. IP masquerading under Linux. I know the FreeBSD
folks have had a NAT daemon to play with for a while. Also, Darren
Reed's excellent IPFilter runs on *BSD, Solaris, HP/UX, and the pre-2.2
Linux kernels (up to about 2.0.35).
