Hello, all.

Have our main house and two rental properties in the back that share internet with us. Purchased a TL-SG105E 5-Port Gigabit Easy Smart Switch for security purposes, as
I want to keep the renters out of our network. I just upgraded the firmware to the latest.

I had imagined that I would run a cable from the modem to Port 5 on the switch for internet access. I want to run Port 1 to my Asus router for my private wireless network, and Port 2 to a Unifi Access Point for the renters (they will share with each other). This seems like it should be easy, but I'm totally baffled and haven't been able to figure out how to accomplish this.

Will someone please take mercy on me and give me some guidance?

Thanks in advance for all replies.

Hi
According to your description, your want isolate port1 and port2. You can configure vlan in TL-SG105E.
Port1 and Port 5 belongs to vlan 2
Port2 and Port 5 belongs to vlan 3
Port 1 can not access port2, both port 1 and port2 are able to access internet via port 5.

Thank you for your reply.

Conceptually I understand that this is what I need to do. I am just at a loss as to how to go about it and the exact settings for it.

Do I accomplish this through Port Based VLAN? I tried that, and only one of the ports worked.

Do I accomplish this through 801.2Q VLAN? And if so, do I also need to configure 801.2Q PVID?

I suppose I am looking for a little hand holding here and need to know the specific settings. As it is right now I'm just kinda trying a bunch of different things and don't really know what I'm doing. It's frustrating because I know this is something easy and I'm just completely missing it. And, once someone shows me how to do it, there's gonna be my palm banging my forehead for being such a dummy!

Setup the MTU VLAN. Working perfectly. Feeling stupid.

Thanks for your help.

Things were working well and then I went and complicated things.

So when I started this thread, I was on AT&T U-Verse DSL. Their modem had a DHCP server and allocated as many IP addresses as needed. As of a few hours ago, I am now on Spectrum, using an Arris TM1602 modem. This modem (I think) will only allocate one IP address.

Originally I had my AT&T modem going right to the TL-SG105E 5-Port switch, then to the MTU VLAN, with Port 1 to my Asus router, and Port 2 to my Ubiquiti Unifi AP-AC-PRO access point to keep us (on the Asus router) separated from our tenants (on the Unifi access point). It was not a problem allocating IP addresses. Now, with the Spectrum modem, it apparently allocates the one IP address to the switch, which will connect to the Asus router with its own DHCP server, but it can't allocate another IP for the Unifi access point. Or at least I think that's what is going on. I can connect Spectrum to the switch to the Asus router, and it works fine. But as soon as I connect the Unifi to another port, it kills the Asus and there is no connection for the Unifi either. If I just try to connect the Unifi it doesn't work (I know will need to assign a static IP).

So I'm wondering if it is a lost cause trying to configure things with the current connection setup. And, if so, is there a way to set this up with existing equipment so it's modem to Asus router to switch to access point, passing through internet traffic but not allowing intranet connections from the access point through the Asus router. I suppose I could cheat it with an old spare router as a DHCP server directly behind the modem.

Some experienced guidance would be greatly appreciated. Thank you for all help.

Your reply reinforces what I was thinking. What I didn't make clear is that AT&T wants their old router back. Yeah, the U-Verse was a router but I had disabled their lousy wifi equipment (they didn't even carry routers with 802.11n several years after N was commonplace) and used my own router behind it, so it is gone. I have a few old routers at another home, and I will grab one and use it as a DHCP server in place of the U-Verse using more or less the old working setup I had before.

You have confirmed my suspicions. At least with all the troubleshooting I did before making that last post (HATE not being able to figure stuff out on my own) I've gained far more networking knowledge. Making mistakes and tinkering is the best way to learn for me.....also a good way to lose hair and raise blood pressure.

Thanks again for your quality advice and help.
