Isolate Guest Network on AP
-
@cburbs Have a look at the vlans section of the pfsense documentation. Good stuff. Also LOTS of good threads here on the forum. You have to sort through the noise a bit, but lots of good advice can be found.

@jwj said in Isolate Guest Network on AP:
I have heard, never seen pcaps to demonstrate, that some TP link switches and AP's leak packets to the default vlan. That's a problem. Question is which switches and AP's have this problem? Has the firmware been updated to fix it for some models. Which ones.
In the end, you get what you pay for.I don't know the problem exists with all models, but certainly the low end managed switches and AP have it. You can get similarly priced gear from other makes. The problem I experienced with my AP is that multicasts leaked from the main LAN/SSID to VLAN/2nd SSID. This made it impossible to use IPv6 on my guest network.
-
@jknott Well that is a problem. Goes beyond just sloppy...
I have a couple of unused TP-Link switches in a closet. Kinda want to sell them off but also don't want to pawn them off on someone who will then have problems. I'd just trash them but that's not very responsible either.

@jwj
One application where they're fine is as a data tap. Since it uses port based VLANs and not tagged, the problem doesn't arise.

Ok so I now have 2 Wireless networks setup on the DDWRT AP.
On the pfSense box I setup the two Vlans
On the switch I want to plug the AP into port 7.
But when I do the above I am still getting an IP from the pfSense DHCP and not from either of the Vlans.
-
Did you set up DHCP servers on each of the VLANs? I assume you have different SSIDs for the VLANs.
-
Correct - Vlan 50, enable DHCP, set IP Range, etc
Different SSIDs for the vlans as well.
can I connect any port from the AP to Port 7 on the switch?
-
The ports connected to both pfsense and the AP have to be able to pass the VLANs. For example, my guest WiFi is on VLAN3. So, I configured VLAN3 on pfsense, my AP and on the appropriate switch ports.
-
In the switch you need those VLANs to be tagged on both the port connected to the AP and the port connected to pfSense.
And you need to remove port 7 from the default vlan, unless you have a third SSID there that's untagged.
However the fact you were still pulling an IP from the LAN subnet also suggests those new SSIDs are now using the VLANs correctly in the AP.
Can we see an ifconfig output from the AP?Steve

@stephenw10 Sorry I was wrong on that no IPs while connected to the ddwrt ap wireless.
Something still wrong with my config and trying to look at this as somewhat of a reference point - https://www.tp-link.com/us/support/faq/788/.
This is what I am after as a test ....
So Pfsense plugs into Port 1 on Switch.
Asus AP(DDWRT) plugs into Port 7 on Switch.Two Vlans setup on DDWRT
SSID: Mobile - Vlan 50
SSID: Guest - Vlan60 -
Yes, so the in the switch config VLAN IDs 50 and 60 need to have both ports 1 and 7 as members and tagged.
-
Ok got a step further and I have the Vlan60 working which would be my guest network.
So Vlan60 just needs internet access nothing else.
Right now I just have two rules in my test bed on this Vlan.
Allowing Vlan 60 clients Internet Access
Block Access to Lan when on Vlan60.
Allow Access within Subnet
Am I missing anything on this?
-
Access between devices in the same subnet is not required, that doesn't go through the firewall.
Devices there may need access to the firewall itself (VLAN60 address) for DNS and NTP etc. Otherwise you probably want to block access the all other IPs on the firewall itself and all other local subnets.Something like this:
The Private_Networks alias there is just 192.168.0.0/16 in my case. If you have mutltiple subnets in an alias I would recomend using block then pass rather than pass invert like that.

Great I will have to look into that a little later.Thanks for everyones help on this so far!

Wow way too much time spent on this lately but finally getting it to where I want it to be.

I am sure I am forgetting something.
