Hello!
I've installed the FreeBSD 2.2.2-RELEASE on three PC (Gateway2000 P5-100)
to make a Firewall.
But there is something strange with my Ethernet adapters   :-(

There is my schema:

                             |                        |
                             |                        |
          x------------x     |      x------------x    |
   <------X ext_router X-----X------X int_router X----X
  to my   x------------x     |      x------------x    |
 provider                    |                        |       x----------x
                             |                        X-------X mail_hub |
                             |                        |       x----------x
                             |                        |
                             |                        |       x----------x
                             |                        X-------X  client  |
                                                      |       x----------x
                                                      |
                                                      |

All computers have FreeBSD 2.2.2-RELEASE.
ext_router and int_router have two Ethernet adapters: 3Com 3C900 and SMC
80xx.
mail_hub have 3Com 3C509 Ethernet adapter.

Now I try to describe my problem:

When I try to download a file from ext_router to int_router via FTP,
transfer rate is around 700 KBytes/sec. The same transfere rate is when I
try to transfer a file from int_router to mail_hub or even from ext_router
to mail_hub!
But if only I try to UPLOAD a file from int_router to ext_router, then
transfer rate is only around 200 KBytes/sec!   ;-(((((
I have only one question: WHY?

There is output of command "ifconfig -a" on int_router:

vx0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 193.125.114.36 netmask 0xffffffe0 broadcast 193.125.114.63
        ether 00:60:97:b5:f6:37
ed0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 172.16.10.35 netmask 0xffff0000 broadcast 172.16.255.255
        ether 00:00:c0:50:6d:c3
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
        inet 127.0.0.1 netmask 0xff000000                                  
  

Maybe, a SIMPLEX flag is wrong?

HELP ME!
It's very important for me!

If you answer me by email, it may be more fast!

PS: I'm so sorry for my English  :-(

Yours sincerely,
Pavel
