Hello all I'm building a filtering bridge with FreeBSD
4.5 and ipfw.
Reading in the article "Filtering bridges" of the
handbook I find in the firewall rules section:
# Pass the "quarantine" range
${fwcmd} add pass tcp from any to any 49152-65535 in
via ${oif} setup keep-state
oif is the external interface linked to the router.
What is "quarantine" range?
I mean, why let ports between 49152 to 65535 be
opened?
I prefer to close them, or is there some motivations
to let them opened for external
connections?
