Do you know if Livingston Portmasters have the same problem?
I am seeing corrupted packets arriving at my Ascend Pipeline 50
from my ISP's Livingston PortMaster (don't know the model).
Most packets make it through, but I see certain packets in
FTP and HTTP connections that never make it through the
port master.

Thanks,
++Brian
