AirVPN installed, where to go from here? & Unknown IP being blocked

  • Hey all, I am currently running Pfsense with AirVPN. The trouble I am having is there are certian IPs that are being blocked and I am not sure how to figure out what they are attached to and what they are intended for in my network. I pinpointed a few bloatware apps and promptly uninstalled and have cleared their notifications, but now I am stuck with other messages., and are showing up, in fact 52%(the nifty graphs in the web interface are awesome) of the messages are just for those IPs. Various ports are being blocked… I know that the IP is associated with a sort of call all function, but I do not understand what would need to do that. If it is valid, why is it blocked?

    I am a noob, and I am running this as an educational project. So pardon my ignorance or lack of understanding.

    What other things should I look for or understand to utilize my system better.

    4gb ram
    PFsense is installed on a USB, will change to SSD later once I have this all sorted.

    Performance is needed so I can use my VPN at full speed. The machine was also $50, so couldn't beat that. I have tried to run a VPN on a router before and my speeds went from 220mpbs, to 10.

  • I ran a packet capture, and found that my bios is trying to communicate with my network? Digging more….  :o

    My Network:
    Modem < Wifi Router < PFsense box < PC - Temp setup as I get my configuration in order, then I can connect the box to the modem.

  • Third update..

    So after digging and digging and digging… I found that netbios is enabled by default, and is not a necessity. It was being blocked by the rules set through LAN. I had to change the adapter settings on my windows machine so it would stop trying to ping through LAN.

  • Another update.

    I have learned that the rules that I have set caused the block… I also learned a whole slew of other things. Firewall is working as intended, as well as VPN.

    My pfsense box is up. Modem < Pfsense < Wifi AP < Devices
