Any reason not to just use Comodo Firewall's default settings?

I’ve only installed the firewall since I have Zemana running real time. I’m behind a router, browse 99% of the time sandboxed with Sandboxie, have WOT installed in Firefox and have a good A-V (Norton). Last but not least, I’ve rarely ever even been alerted by A-Vs, and never since observing WOT’s recommendations. After having said all of that, still open for suggestion if you don’t feel defaults are enough! Thank you!

I would certainly switch to the Stealth mode in CF even in such a good protection suite.

While you should be pretty good with those measures setup, enabling stealth mode takes about 5 seconds and if you’re on a laptop that you travel with as your main computer (like me) then it could be a life saver.

Just go to “Firewall” and then “Stealth Ports Wizard”, then click the third option “Block all incoming connections and make my ports stealth for everyone”.

Will do! Thank you both!

Should I enable “Protect the ARP Cache”? Thank you!

As you’re behind a router you don’t need it. Open a command prompt and type arp -a to view the arp entries.
