Netgear/Vlans/Pfsense

@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!!!!

This is my windows box arp table... Post yours up from the BOX connected to port 1 of your switch! if on that box your seeing 192.168.1 IPs then your setup is BORKED!!!

And post your ipconfig /all

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

BORKED! LOL

johnpoz

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:

Clear your arp table

cleared and not returned

cannot ping any 192.168.1 or 192.168.5

i have the following arp entries now

192.168.5.1
192.168.5.255
224.0.0.22
224.0.0.251
224.0.0.252
239.255.255.250
255.255.255.255

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..

Yup... So lets see your rules on on vlan 5 again... And do you have any rules in floating?

r79c

https://ibb.co/rs4tG8r

https://ibb.co/zVDwqW4

johnpoz

So your blocking it with pfblocker... Disable those rules on floating as test!

That firehol list contains rfc1918 address space!!

r79c

Ok I disabled those rules and disabled pfblocker for the time being.

I set those rules up when I set up pfblocker but I was never 100% competent on how it is setup, I only set it up about two weeks ago....

johnpoz

And - are you pinging?

r79c

@johnpoz said in Netgear/Vlans/Pfsense:

And - are you pinging?

no

johnpoz

Well your firewall rule that allows all of IPv4 show hits... And your seeing the traffic actually hit pfsense vlan interface... You were sniffing on the vlan interface right!! not lan..

So lets see your routing table..

Unless you where not sniffing on vlan 5 interface it makes no sense to be honest..

Is pfsense a VM? Or this is a physical box... What is the nic of this box? Why does the mac of the 5.1 not show as known company?

Well that looks correct.. you have 192.168.5 and using the interface..

And it was seeing traffic - your not running any sort of IPS are you?

Can you post output of
