Hold on a sec. You've got 17 devices plugged into a switch with 16
ports. Unless the switch also has some kind of "uplink" port AND the
Internet server has some way of plugging into it, this isn't going to
work.
[Although I cannot find details of a 16-port switch in 3com's
OfficeConnect line, other devices in this line do not seem to have
uplink ports, and in any case the DP-602 connets via 10/100 Ethernet.
I'm about 86% certain that it's going to count against the total of
16 ports on the switch.
An alternative you might consider is to go with a 4-port switch;
plug the DP-602 into one port and a couple of 9-port (8 + uplink)
hubs into other ports, or two 8s and a 4 without uplink ports.]

A switch is like a multi-port bridge. If you had six of the PCs on
one side of a network bridge and ten on the other, and no session
traffic across the bridge, then only broadcasts would cross. Same
thing here; odds are that the game produces little broadcast traffic,
so impact should be minimal. [If the switch supports VLANs, and if
it makes sense to split your network into two, you can reduce this
impact even further....]
