Ed,

These devices usually have some default firewall settings which  
probably need to be adjusted. They will generally have some browser  
based configuration tool but the different manufacturers all have  
their own way to describe their features so its difficult to give you  
precise instructions. However, look for a setting that allows (at  
least) incoming traffic on ports matching a port for existing outgoing  
traffic.

Also, you may find that you'll have to increase the incoming bandwidth  
limit; this is often set quite low by default on the assumption that  
that a very high incoming traffic rate indicates a packet storm -  
possibly a denial of service attempt).


BTW if you're relaxing firewall rules on a network containing any  
Windows machines, ensure all available service packs, hotfixes etc.  
are installed or you'll be owned really quickly.
