I am behind an ADSL modem/router, which provides a hardware firewall. I
do not see spurious packets on my LAN as a result. My LAN uses switches,
so only packets destined for my IIgs, or universally addressed packets,
get through to it.

If you have a Mac, you could try running EtherPeek, and if you have a
PC, try running Ethereal. Both of those will show you what kind of
spurious packets may be arriving on the LAN. With no activity on the
IIgs, or the computer monitoring the LAN, you should only see a few odd
packets now and again. If there is a constant flood, the you would be
able to see which ports they were going to, so you could set up a
firewall to block them.

If it is indeed flooding with spurious packets, the analogy is trying to
use too fast a dial up modem baud rate, and getting data corruption as
the interrupt system on the computer cannot keep up. An unaccelerated
IIgs has difficulty keeping up with the fastest modems. 

Although the Uthernet card has its own onboard buffer, this is of a
finite size, so a continuous stream of packets might easily overload it.

Solutions to this problem would be a hardware firewall before the
packets could get to your IIgs, an accelerator for the IIgs so it could
better handle the data, or switches on your LAN rather than hubs, again
to filter out spurious packets.
