I added a rule to one of the vpn interfaces that I have outbound

https://ibb.co/4TspV7G

Is this correct?

johnpoz

Again those wan outbound hybrids are POINTLESS!!!

And how you sure that outbound nat is gong to use that vpn interface, if your policy routing it out a group... What if it goes out a different vpn interface?

r79c

So i have the following configuration and I still have no internet connectivity on the pc plugged into port 1 on the netgear switch. The VLAN5 interface is up, I have outbound NAT rules and firewall rules in the VLAN tab. I just dont understand it at the moment????? It should be relatively simple.

on the pc i get a dhcp lease but am unable to ping 192.168.5.1 or google.com

LAN is on 192.168.1.
VLAN is on 192.168.5.

here are some more screens of the configuration.

I've just read that you cannot send vlan over vpn!

Not sure how that NordVPN stuff works, but I think you need the 192.168.5.0 natting out the VPN gateway instead of the redundant WAN. Why don't you just verify the vlan works out the WAN first. I'll refrain from giving my opinions of 'privacy' vpn providers.
RE: That last link, i'm not sure what JP is on about- you can't carry the vlan tag over a VPN, but you can absolutely have a vlan interface with a unique subnet and route that. My experience however is with site to site tunnels.

r79c

I thought that as well, getting it to work with the WAN first so I added the following mapping...

https://ibb.co/WF4NFYm

still no internet, It has to be something stupid that I'm not configuring properly...

Well then look to the client for why... Can you arp pfsense 192.168.5.1 on the client? You have no rules allowing to ping pfsense.. Its possible everything thing is getting shoved out your policy.. So no you wouldn't be able to ping 192.168.5.1... Create a rule above your policy route rule that allows ping to vlan address

I've just read that you cannot send vlan over vpn!

Your reading that WRONG... That has nothing to do with what your doing, which is routing a specific network/vlan over a vpn connection.

As to getting to the internet - well how and the F do you think its going to go out your vpn which your forcing via your policy route.. But your not natting to it... We already went over this!!!

What I would highly suggest you do is get your vlan 5 working as a normal network before you worry about shoving all its traffic down some vpn connection.

@johnpoz What I would highly suggest you do is get your vlan 5 working as a normal network before you worry about shoving all its traffic down some vpn connection.

that's what I'm trying to do

@johnpoz Create a rule above your policy route rule that allows ping to vlan address

By policy route rule you mean a firewall rule in the vlan tab that allows me to ping vlan address?

if i do arp -a 192.168.5.1 i get

Interface: 192.168.5.0 --- 0x7

Physical Address MAC

@r79c said in Netgear/Vlans/Pfsense:

I dont get a response with arp 192.168.5.1

Look in your client that is on this vlan 5, look in its arp table.. If you do not see pfsense mac address then NO your never going to be able to ping it.

And would say your not getting dhcp from it either..

I am assuming this is a windows box.

lets see its ipconfig /all
ping 192.168.5.1
look in your arp table
arp -a

This is WRONG

Interface: 192.168.5.0 --- 0x7

Post your ipconfig /all

Your interface sure and the hell should not have a .0 address with a /24 mask.

r79c

arp -a on the client gives me

Interface: 192.168.5.50 --- 0x7

johnpoz

Well is the mac address for 5.1 pfsense mac address. Where were you seeing 5.0? for your interface?

You have something really F'd up

192.168.1.125
192.168.1.201
192.168.1.202

You shouldn't be seeing 192.168.1 address if your in vlan 5!!!

r79c

@johnpoz yes the mac address for 5.1 is the mac address of the lan interface

5.0 must have been a typo

two of those 192.168.1 address are static IP mappings for devices
192.168.1.125 is the IP address of an access point

all these IP addresses go through port 3 on the netgear switch which is connected to a wireless access point mesh

johnpoz

@r79c said in Netgear/Vlans/Pfsense:

Doesn't matter! So you created those on the device directly with arp? For why? It is pointless, and does nothing - sure and the F not going to work..

I take it basic understanding of how vlans actually work, and what they do is where we need to start..

r79c

@johnpoz So you created those on the device directly with arp? For why?

I statically mapped those IP addresses using Pfsense with arp yes, why, because those two devices are TV's which I did not want to put the traffic over VPN connection.

@johnpoz I take it basic understanding of how vlans actually work, and what they do is where we need to start..

sure, your the only one responding to this, and I'm grateful because I can't seem to get this working at all!!! I'm starting to wonder why I'm bothering really, as I only wanted to setup up one VLAN with one PC on my home network LoL

Dude ON THE CLIENT!!! we need to see the arp table on the CLIENT that is in vlan 5 and connected to port 1 of your switch... Not the arp table of pfsense!!!!

At a loss to where your posting that arp info from - because that sure and the F does not look like how pfsense would present it..... And no matter what you did with static arps on pfsense they would not show in your clients arp table.. You do not have your vlans setup how you think you do if your seeing arp entries from 192.168.1 on your box that is suppose to be in vlan 5

This is switch setup
pfsense - 1U,5T --- switch --- 5U --- vlan 5 client

If that is how you have it setup, you should NEVER see arp entries for anything other than what is in vlan 5

Yup that is BORKED

You should not be seeing 192.168.1 address if your in vlan 5.. So your switch is clearly not setup correctly. or its not doing what it should be doing.. If you were in vlan 5 it would not be possible for you to get arp answers for anything in 192.168.1

r79c

@johnpoz said in Netgear/Vlans/Pfsense:

This is switch setup
pfsense - 1U,5T --- switch --- 5U --- vlan 5 client

If you could look at the following pictures they show the netgear switch setup as it is at the moment.

https://ibb.co/0ft99fJ
https://ibb.co/D9W0ZXV
https://ibb.co/wy401MF
https://ibb.co/z7Rv26Z

Pfsense is plugged in to port 2

VLAN5 PC Client is plugged in to port 1

Everything else is plugged into port 3

johnpoz

that looks correct yes..

But its not working if your seeing mac of devices in 192.168.1..

Clear your arp table... Do they come back? trying pinging one of those 192.168.1 address from your client after you clear your arp.

BTW your rules on vlan 5 are WRONG!!! source would NEVER be pfsense on vlan 5 address.. Source would be vlan 5 net..

What did you set netgears IP too? You said you changed it.

What is the hardware of your pfsense box?
6DB311

That doesn't resolve as maker of networking gear..

r79c

@johnpoz said in Netgear/Vlans/Pfsense:

cleared and not returned

cannot ping any 192.168.1 or 192.168.5

johnpoz

Ok that is better!

So simple test is sniff on pfsense vlan interface while you ping it from the client.. Do you see the ping?

BTW what hardware is the nic on pfsense? that mac doesn't resolve to anyone..
