    Jay, thanks for sharing your early experience being confused by submitting, vlans, and segmentation. That was true to my experience, but nobody would guessed that you ever had trouble. I think it's important for folks new to it to know it isn't always easy to understand right out of the gate.
    We all have to start somewhere, so just keep poking at it.

    Just managed to watch it now due to time zone difference. But will still listen through every morning.

    You answered my "stickler" question. If you subnet everything up, how do you stop forcing everything through the router.
    Answer: Put devices onto more than one vlan/subnet directly. Then they can access it layer 2 without routing.

    Wow Jay, when it come to subnet addressing and the schema of network devices we must have been cut from much of the same cloth.

    Speaking of "Not segmentet by default", its important to remember the difference between a router and a firewall. A router is not suppose to segment by default, thats the firewall behavior. On a router we primarily divide networks, to limit the size of our broadcast domains.

    Can you please do an in-depth video on UniFi remote adoption and port forwarding ports for cloud key with the fully qualified domain name override and how to preset up the units before deploying them so when they are installed at the customer site that they automatically reach out to the cloud key thanks again

    while preventing broadcast storms is cool and all....there is certain traffic that needs broadcasts such as DHCP for discovery. when splitting the network you may need "ip helpers" to advise clients on the different segment the location of the DHCP service

      I don’t know how it’s done elsewhere, but in pfSense each VLAN or subnet gets its own DHCP server. So at least no broadcasts necessary for that.

    Haven't checked your channel out yet, but I'm excited to see it! Does someone need to watch the past 40 episodes from the beginning or can we jump around? Thanks!

    Very informative thank you …. I’ve been playing with my network trying to add a pfsense box to use with my UDM Pro has been a fun endeavor to say the least . I wish UniFi didn’t cripple a mostly great device lol ended up trying to make a vlan only network on the UDM and then tagging all the ports I want on all my switches to that vlan and then plug the pfsense box to one of them to use it’s DHCP server . And then double NAT the UDM Pro . Still testing it to see how it works and leaning in the process

    What's the name of the standard? RSV-19 or RSB-19? Where do I find more information on the standard itself?

    • @stevenmishos

      RFC1918

      @teqik 2 ปีที่แล้ว +2

      Thinking of RFC1918? The private IP standard, concerning the 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16 network prefixes?
      For some reason YT removed my answer with the URL to the the whitepaper, but if you google IETF or just look on the ietf dot org site for the RFC1918 page you'll find all the gloriously dry details.

    If you “need” to segment your network to control WAN congestion, you obviously lack QoS on the firewall.
    Even easier: Simply configure a limit, per port, on the Ethernet switch.

    I am hoping you can revisit SyncThing set up AND Unifi USG setup, with phone. If phone is on a separate network, relay enable has to be turned on in SyncThing. If relay enable is turned Unifi detects threats.

    • @LAWRENCESYSTEMS

      I never use the USG routers but my guess would be you need to turn off threat detection

(With phone on separate LAN and relay enable set to on). For now I am switching network briefly just to sync. I debate if syncing with on the same network or syncing using SyncThing relay servers is least secure.
