The 10baseT hub is builtin to the Efficient router, guess I should have =
explained that originally.
The reason I use two nics is the fact that the Efficient only supports =
10mb, and I want 100mb on my LAN. So rl0 is my outside interface, =
running at 10mb. The internal interface, rl1 is running at 100mb and =
connected to my 2 windows machines via a 3com 100mb ONLY hub. As you =
can see I am somewhat limited in my hubs, a 10mb only hub and a 100mb =
only hub.. :) so that is the reason I have the setup I do. If I had =
better hubs, I suppose I could just alias the two addresses, but none =
the less.
I do have two nic cards installed, two realtek type cards (don't have =
specific models)
rl0 (outside) 216.36.73.6
rl1 (inside) 216.36.71.1
win98 box 216.36.71.2
winXP box 216.36.71.3
216.36.71.x is my internal subnet
216.36.73.6 is part of a /30 block, no other machines are on this =
subnet, just the router.
Apache originally was only setup to listen on rl0 (outside). I thought =
I may have had some type of routing issue which was causing slow =
performance. So I setup Apache to listen on the inside too.=20
My reasoning as to why it is not Apache but some type of OS =
configuration issue would be that I get similiar bandwidth patterns via =
FTP.
Thank you for your response. Let me know what you think.

Subject: Network Issue
=20
I apologize if this message has been sent to the incorrect list.
To anyone that may assist,
I have an issue on a FreeBSD machine acting as a firewall/router =
with 2
NICs. Here is my configuration
Running 4.3-release
Pentium 2 - 350mhz, 128mb RAM
6gb hard drive with less than 25% used on all slices
2 network cards, Realtek type, (rl0 and rl1)
Routable IPs on both interfaces, using routed
rl0 200.200.200.6, default gateway 200.200.200.5
rl1 200.200.201.1
2.3mb SDSL line
IPFW is running, no queues enabled. Basic port blocking only
Running Apache 1.3.20 on rl0
Physical setup:
DSL line -> Efficient Router -> Hub (10baseT) -> FreeBSD (rl0) ->
(routed) -> FreeBSD (rl1) -> Hub (100baseT) -> Local Machines
Tests
Win98 machine at 200.200.200.2, goes to internet server and downloads =
file
at full bandwidth.
WinXP machine at 200.200.200.3, full bandwidth when going to popular
download site on the net.
Win98 machine to Apache server running on rl0, download 30-40k/sec =
max.
Win98 machine ftp to rl0, download 30-40k/sec max, upload 600-700k/sec
WinXP machine to Apache server running on rl0, download 30-40k/sec =
max.
WinXP not tested on ftp to rl0.
External machine (a friend) running Win98 to Apache server running on =
rl0
via DSL, download 150+k/sec.
So I am deducing there is a problem somewhere in the routing of data =
between
rl0 and rl1 to my internal Win98 machine since it is affecting not =
only http
but ftp traffic as well. I have tried removing all IPFW rules to see =
if
maybe they are clogging up the system, no change.
I have asked a few other more experienced admins to see if they have =
any
ideas. Besides suspected hardware issues no ideas come up.
Any ideas? I am dying here! :) Thank you for any response and again =
I
apologize if this was sent to the wrong list.
