If you find that outgoing traffic crawls along no matter how high you
set the bandwidth, then you can apply this workaround. Install the
'ethtool' package, then in /etc/shorewall/init, add this command:

        ethtool -K ethX tso off gso off

where ethX is the affected interface.

This workaround turns off TCP segmentation offloading and Generic
segmentation offloading in the NIC.

I'll be working on a better approach that will allow this offloading to
be re-enabled.
