Setting up a VLAN part 2

A Former User

Was the case that you have your LAN in vlan1 and WIFI in VLAN100 and in same interface?
if so then your settings on switch should be
VLAN 1: U N and the rest U
VLAN 100: T U and the rest N

Legend:
U = Untagged
T = Tagged
N = no access or similar

yes, exactly.

i will try to set it up like this and report back.

EDIT- my switch (netgear, not vlan ready) is in port 6 of the vlan switch. how should i handle that? U for vlan 1 and N for vlan 100?

You can certainly do this with one interface and run just about as many vlans on it as you want.
You should avoid tagged and non-tagged traffic if you can but it may well work just fine if you can't. Since you're just experimenting it's not a problem so go for it.
That said what I would do is put your LAN traffic on a VLAN also so that all your traffic is tagged. The difficulty with doing this that if you get the config wrong you can end up locked out of your box and it quickly becomes frustrating when you keep having to start over.
Why not setup your extra interface just as a management interface. Make sure you can always get back into the box via that.

There is some confusion here regarding VLAN1. The is the default VLAN which I believe is actually just untagged? (at least outside of the switch) To avoid this always use high numbers, like VLAN100 you are already using.

vlan 1 is just the default vlan of the hp switch.

i am still getting confused with the tagged/untagged. everytime i think i have it and try to see if what i get matches up with what is said on here, i am always opposite.

when i am all done with this, i want my HP vlan switch to be accessible via the IP it has, now, which is 192.168.1.20, i dont need to be able to access it from the vlan network (but that is another question at another time).

what i am wanting to do/test is to have 1 cable connecting my pfsense and the hp vlan switch and over that 1 cable i want to have 192 and 10 traffic. then, assuming the hp switch is setup properly, i want to do the following

port1- pfsense LAN
port2- test laptop or wifi router (statically assigned 10.10.10.2 for access at a later time) 10.10.10.x network (vlan 100)
port3- cant use (trunked/bond)
port4- cant use (trunked/bond)
port5- connects to a PC i want to keep on the 192.168.1.x network
port6- connects to my 16 port netgear switch that has additional 192.168.1.x devices
port7- open (no need for vlan100 access)
port8- open (no need for vlan100 access)

Yes like that, if you have switch which doesn't have vlan capability, then you connect that port like any computer.


Port 1: vlan1 untagged, vlan100 tagged <-- best method would be tagged/tagged, but then you should use stephens method
port 2: vlan2 no access, vlan100 untagged
port 3: ? 
port 4: ?
port 5: vlan1 untagged, vlan100 no access
port 6: vlan1 untagged, vlan100 no access
port 7: ?
port 8: ?

whoa, where is vlan2 from?

edit- typo, right? that should say vlan1, i assume.

A Former User

N for no access is the same as E for Exclude i would imagine.

my HP uses T, U, E

stephenw10

Yes N==E. ;)

Just take it one step at a time. Varify that each step is doing what you think it should. Most config problems are caused by trying to implement a hundred functions at once and then, when it doesn't work, having no idea which one caused the trouble.

Steve

Metu69salemi

You're right it was a typo. And N just meaned that anyway there is no connection between, so it doesn't matter what is the language of your switch

A Former User

ok, i set it up as posted but still not getting a 10.10.10.x ip on the spare/test laptop (plugged into port 2 on hp switch).

here is what the switch and pfsense look like

A Former User

one thing to note, the 192 network is working with this setup.

when i did this last night, i couldnt get 192 or 10 to work, so i am getting somewhere with the tagging/untagging/excluding.

i should also note that both yesterday and today (prior to messing with this) the pfsense lan cable re2 plugged in directly to my netgear.

once i started setting this up, i made sure to unplug re2 from my netgear switch into port 1 of the hp switch (vlan switch) just in case someone thought that wasnt happening.

thanks

stephenw10

Hmm, that's not right. Set the participation as Metu69salemi suggetsed earlier.


Port      1 2 3 4 5 6
VLAN1     U E * * U U
VLAN100   T U * * E E

If that doesn't work try:


Port      1 2 3 4 5 6
VLAN1     T E * * U U
VLAN100   T U * * E E

ok, the first config doesnt give my laptop an IP, but 192 network can go online

with the second config…i get no ip to my laptop and 192 network cant go online.

EDIT- if my pfsense settings look ok, then i can stop looking there. do you guys want pics of the DHCP server settings? i set it up the same as 192 DHCP settings, so anything plugged into port 2 of my vlan switch should get an IP address from 10.10.10.x from pfsense.

stephenw10

Ok stick with the first config then.
You may as well post your DHCP config, it might help.

What exactly are you using ports 3 and 4 for?

Have you added firewall rules for the vlan interface? I assumed you had. DHCP should work anyway.

The confusing thing here, for me, is that a packet tagged with vlan ID 1 is not the same as an untagged packet.
It shouldn't be this difficult so something is obviously wrong somewhere!

ports 3/4 are trunked/bonded to my NAS. just trying to get the most i can with two cat5 cables. the nas also has a 'bond' with the two nic ports.

here is the DHCP screen shot for 10.10.10.x and i have not written any firewall rules, i agree with you in that it should still assign it an IP address.

Metu69salemi

can you show your rules of wifi interface?

and still i'd like to use that


port:        1 2 3 4 5 6 7 8 
vlan1:       U E U U U U U U
vlan100:     T U E E E E E E

or then go the later solution(port 1 tagged in both vlans), but you'll have to setup management on other nic and networks in other nic

stephenw10

This could be the reason the tagged and untagged traffic should not be on the same interface. ::)
I have not experienced how problems would show up.

Steve

Edit: Reading 'the definitive guide' for inspiration I see that this could be a problem related to the NIC not supporting the increased frame size required by the VLAN tag.
In particular it mentions that Realtek interfaces may not support it even if they report doing so. Though that is for rl(4) rather than re(4).

ok, i will take a look at that setup and report back.

also, unless some default rules were put in place, i didnt create any rules, but i will post a screen of that and add in some common/default rules to see if that does it.

if the above config doesnt work, i am going to stop trying to do it with 1 NIC and will bring in the second nic.

Here is what I would do:
Disable trunking/bonding for now, it's just adding a further complication and you can add it back once you figure out VLANs. (what VLANs did you set on the trunk in the switch?)

Setup the second interface so that you have access to the webgui even if everything on the first interface gets locked out.

Unassign the first interface so that it's not sending untagged packets. Create a VLAN on it, VLAN100 say, and then try to configure the switch to work with it.

Add more VLANs once that's working.

everything you mentioned is my problem (tagging/untagging).

since i get confused, i wont know if i am doing it right.

not sure how to setup management to be accessible from both vlans?

also, you can see how the trunk was configured in the pics above. i dont think there are issues with that, worst case scenario (if i set it up wrong) i wont be able to access my NAS, not critical.
