Ah, looks like a BSD box. From the ifconfig manpage:

     -rxcsum, -txcsum
             If the driver supports user-configurable checksum offloading,
             disable receive (or transmit) checksum offloading on the inter-
             face.  These settings may not always be independent of each
             other.

So you could also try

   ifconfig em0 -rxcsum -txcsum

to see if that helps.

What version of BSD is the client running?

may also be relevant.

Brian.
