      I have a basic understanding of networking and not certain the 3100 is what I need. I’m looking to segregate my home network isolating 1 “work” pc that requires dhcp. It only needs internet access and nothing else, but it requires vpn connectivity to an external target.

      Currently I have the inside int of the modem to a Linksys wireless mesh(single internal port also serving dhcp I assume with some type of PAT). This is hooked into a 8 port unmanaged switch serving multiple home computers and one work computer.

      What I would like to have is inside int of the modem hooked to a 3100. 3100 opt1 port connected to work computer only. LAN port from the 3100 hooked to a 24 port unmanaged switch. The switch serving the linksys wireless and multiple other computers.

      My question is can the opt1 port serve a separate dhcp scope than the lan ports? Can it handle 2 dhcp scopes at all? I believe I could go another route and just use a managed switch, but I still need something serving addresses via dhcp and I like the idea of having a pfsense firewall in a small form factor appliance.

      I read through the guide and noticed dhcp could be configured on opt1, but it didnt speak to the lan ports or any type of pat/nat(regardless i never understood the claim of “nat” on soho wap since its not a 1 to 1 translation of ips)

      Any help would be appreciated.

        Yes you can have one DHCP Server per LAN/OPT interface with no problem.
        If you only need 3 ports in total check out the SG-1100: https://store.netgate.com/pfSense/SG-1100.aspx

          Appreciate your response. 3 ports is really only what I need right now. I had noticed the 1100, but wasn’t sure if there would also be a performance decrease. If the 3100 vs the 1100 was simply an increase in port count then the 1100 may be the model for me. Sincerely appreciate your response.

            The difference from a SG-1100 to the SG-3100 will be the supported speeds, What is your WAN/Internet connection speed.

              Well both can do 1 Gbps throughput. ☺
              Sure if you want to run lots of additional packages the SG-3100 would be a better choice.

                Who and the F makes a 24 dumb switch?? Never heard of such a thing.. Biggest dumb switch I have ever seen is 16 ports.

                Oh looks like trendnet makes one - what a F'ing waste ;)

                Oh looks like netgear does as well - who would be in the market for these? Wow... Do yourself a favor and get a "smart" version.. Get one off ebay or something if you have budget constraints.

                    Internet speeds are like 250Mbs here so sounds like either the 1100 or the 3100 would work.

                    As far as the unmanaged switch it’s simply a cost factor for me. I do not need anything other than a “splitter” to multiple devices basically. More than likely most of the ports would be inactive, but my house has about 18 drops in various rooms that I would just rather have connected.

                    I’m not a networking guy so it’s possible I’m mixing up the terms. Amazon has numerous 24 port unmanaged switches..

                      And then tmrw your going to want to isolate X from Y, etc.

                      I can understand a budget issues - find yourself a nice "smart" switch off ebay for your budget.. You can for sure just use it as dumb switch today... But tmrw when you need to create a vlan you will be able to.

                        @johnpoz Yeah, I thought about that. I was just trying to cut cost. I need a new tv, an Apple TV, a generac to power my house as I have numerous outages, my kid needs braces, etc..etc..etc..etc

                          We all know budgets... We Get it... But really just find a smart one of ebay if you have to save a few bucks..

                          I would love to have 10ge everywhere - but "budget" doesn't allow :( But just because you need "ports" doesn't mean you should get dumb ports. If your moving into the power of a real router like pfsense, at some not too future point your going to wish you had spend the couple of extra bucks and gotten a smart switch.

                            @johnpoz I’ll give it a look. I really just have that one device I need to isolate though. The only reason I’m even doing that is because that is a dedicated work machine. I can’t think of any reason I would isolate anything else.

                            Crap... ok.. you’re starting to convince me..

                              If a geek gets a vlan capable router, he's going to want a vlan capable switch.

                                So you have all these devices - are any of them IOT? Do you really trust them? You have anything that floods the network with multicast - pretty much any off the shelf soho shit ;) etc. etc.

                                  Not really. Most devices run off wireless. Cabled I have 2 pcs for home .. a printer.. and the one work computer i want isolated. I also have a steam appliance, a smart home hub(homeseer) and prob a few other odds and ends. I was already debating buying a managed switch however. But it was 200 more than a non managed one.

                                    I had to look up IOT and I’m not certain really. The only unusual thing i have going on is the smart home and I don’t like the fact that the amazon echo has to go out to the internet to talk to my internal hub sitting 20’ from it. I have various light switches all connected to homeseer that is controlled via Alexa.

                                      I will prob end up with the managed switch route. You guys are right in that I don’t really have a need for it now(that I’m aware of at least), but I might as well fork over the cash than having to buy one in the future. I was holding out as I figured if i installed cameras too then I would need a separate more expensive switch supporting POE. All of my smart home devices are wireless at this time except the hub and echo. I just can;t think of anything I would want to isolate other than that one computer since all the other devices are isolated to some degree being served over WiFi. Obviously I’m not a network admin however..

                                        For $200 (US?) total I expect to be able to get a pretty decent 24 port managed switch second hand. Maybe even with PoE.

                                        What you probably will get with that though is higher power consumption. But you'd probably have to run a new switch for decades to make that back.

                                        5mins on ebay brings up stuff that.... I'm actually considering buying. 😉

                                          For $200 you could get a cisco sg350.. 28 ports.. Its on amazon for like $180 currently NEW!

                                          On ebay your in the $50 budget for 24 port smart switch, etc.

                                          If all your devices are wireless - WTF you need a 24 port switch for? ;)

                                          If your going to put in lots of cameras and multiple AP then ok poe switch might make sense... But if your talking a handful of them, then you can just use poe injectors.. Especially if your on a budget - because poe switches going to cost you more.

                                          BTW - now as stated that you have a vlan capable router, your going to want vlan capable switch - and goes along with that vlan capable APs ;)
