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? ______________________________________________________________________ Scarica il nuovo Yahoo!
