I've found the same gross inaccuracy with the IN-BANDWIDTH as Brian did. I
changed my /etc/shorewall/tcinterfaces file to:

#INTERFACE      TYPE            IN-BANDWIDTH    OUT-BANDWIDTH
COM_IF          External        100mbit         8mbit:100kb:200ms

With those settings, I get:

Download Speed:  50 -  60 mbit
Upload Speed:   7.8 - 8.0 mbit

Maximum ping times were in the 50-85 ms range, down from over 200ms.

Which is all pretty satisfactory. Setting the IN-BANDWIDTH down to 80mbit
reduced the Download Speed to ~ 40 mbit. Setting it to 40mbit reduced the
Download Speed to 10-12 mbit.
