I think we have the same issue....
Working on this problem for months now and I can't find the problem. I also=
=20
used the FreeBSD as a NATd server for my ADSL(tun0) connection.
I have some other server demons running, but switching them off gives no=20
positive effect on the upload speed (average it's 10 times slower than=
upload).
When I disconnect the Internet the problem isn't solved, so it's not a=20
lookup loop. Problem is not solved by setting all NIC's to 10 of half=
duplex.
This problem accurse with NFS, Samba and FTP so it's not a configuration of=
=20
these demons.
Please replace the Reltek card, because a realtek chip-set based NIC will=20
over preform on a FreeBSD box, courses connection losses and wrong auto=20
media detections.
However I have exactly the same problem using a 3Com for my LAN connection:
# ifconfig xl0
xl0: flags=3D8843<UP=82BROADCAST=82RUNNING=82SIMPLEX=82MULTICAST> mtu 1500
options=3D3<RXCSUM=82TXCSUM>
inet 192.168.0.1 netmask 0xffffff00 broadcast 192.168.0.255
ether 00:04:75:98:d6:bd
media: Ethernet 100baseTX <full-duplex>
status: active
Have tested my HDD speed but this is good (12MB/Sec read and 9MB/Sec write,=
=20
random).
This is genarated with tcpdump during a heavy upload (500MB), I don't have=
=20
a clue what it means but maybe somebody can have a look at this.
# tcpdump xl0
10:38:10.760321 server.zaleo.homeunix.net.netbios-ssn > zeo.1029: . ack=20
3156635 win 65535 (DF)

3158095:3159555(1460) ack 6883 win 63781NBT Packet (DF)
More information about my system is found on Http://info.zaleo.homeunix.net=
=20
(PhpSysInfo)
As you can see a lot of "err" on this device only when I upload to the=20
FreeBSD-Box, strangely there are no collisions on the network and I have=20
tried a direct twisted pair connection.
If you need more specific information please let me know, we are really=20
desperate to solve this problem.
