<h3>Is Emulab Firewalled?</h3>
<p>
Yes. Emulab blocks all of the <i>low numbered</i> ports (ports
below 1024), with the exception of port 22 (Secure Shell). This is
for the protection of experimentors, as well as to ensure that an
errant application cannot become the source of a Denial of Service
attack to sites outside of Emulab. If your application requires
external access to other low numbered ports, please contact us to
make special arrangements.
