One of the two nic cards on my firewall is an nge:

vr0 is connected to my DSL modem. Although nge0 is capable of 1000Mb/s, it
is connected to my 100Mb/s switch and is running 100Mb/s.

If I ftp a bz2 file to the firewall from any host on the IIF, the file
transfers fine and has the correct size, but will not inflate due to checksum
errors. Also, if I try to use ssh to transfer the file I get the following
result:
>cat A.tar.bz2 | ssh -l nobody -e none sling "cat > A.tar.bz2"
nobody's password:
Received disconnect from 192.168.1.254: Corrupted check bytes on input.
I am clearly seeing corrupted data, however, I dont see any corrupted packets:

Also, I can transfer files through the firewall to hosts on the outside
without any trouble. This data must go through nge0 on the firewall also,
but the speed is limited by the DSL modem on the outbound vr0 interface. I
can access the web, send mail, everything else that goes through the firewall
via nge0 works fine, just not sending files directly to the firewall.
I have searched the web and have not found any mention of trouble with
FreeBSD 4.4 and nge cards. I will be replacing the nic card soon to see if
that is the problem, but I wanted to see if anyone out there knows if I am
doing anything wrong first. Have I misconfigured the card or missed
something else?
Thanks,
