Newly installed Firewalla blocks open ports

Hello All,

I installed the Firewalla red and for some reason it blocked all of my configured open ports. Through the app I went to open ports and it showed 0, even though I have 5 configured open ports which were working prior the firewalla installation. Once I disconnected firewalla everything was reachable. 

Why does firewalla block open ports? Is there a way for firewalla to not block any ports but to scan to see if ports are open?

 

Thank you

  Hi

  What mode are you running the firewalla in? Have you provisioned any rules to block anything?

  no other config changes have been made, its running in simple mode. The weird thing is , when I plug it in, it seemed like everything was going great, but then I ran open ports and it showed 0 ports open and nothing was reachable via the configured open ports.

  I will close this issue, since I unplugged Firewalla last night and this morning I just plugged it back in and disabled monitoring on a number of device, just keeping the crucial ones. So far external access still remains. 

   

  One question, can the open port feature scan for none standard ports or just standard ones, I see 1 of 5 open ports show up, one being a standard one. 

   

  Let me know,

   

  Thanks

  The open port scan can only scan the standard ports at the moment.  Reason is, as we grow our user base, the server that doing the scan can't really scan that many ports. (and part of it is, our ISP always question the scan's, and we have to tell them we have the consent of the server)  We may open up the scan to more ports later as we move forward, or find a different ISP.

  The man is watching your traffic huh? I know VZ watches traffic. We will get nasty grams from VZ occasionally. I figured you would be using AWS or Azure to host your services, scalability and programability and all, and I don't believe they are sniffing traffic flows and sending out nasty grams.
