main switch

[BigA]

@johnpoz Please forgive me Im learning here so lets just start with how to get main switch pointed back at PFsense

This look right

[johnpoz]

@BigA well what is pfsense IP on this network.. Their default gateway should point to pfsense.. Are there multiple switches, daisy chained?

But their management interface I take it 192.168.1.x and pfsense is what 192.168.1.1?

If pfsense is 1.1 and that switch is 1.2 then yeah that should work and you should be able to get to it from remote network now.. can you ping the IP? from your 200 vlan?

its also possible there is some security setup, to only allow access to the management gui from local network? I don't have a tplink like that.. Only a cheap l2 smart vlan model, which has not as feature rich as that one.

I am accessing that switches gui from my 192.168.9 network, you can see its on a 192.168.7 network

If pfsense is 1.1 and that switch is 1.2 then yeah that should work and you should be able to get to it from remote network now.. can you ping the IP? from your 200 vlan? The Only IP that I can Ping is the IP 200.1 Pfsense. 100.1 Pfsense 1.1 Pfsense. Cannot ping anything esle Thats when I on the VLAN 200 network

@BigA so you can not ping pfsense IP 192.168.1.1 address from your 200.x device?

Oh you can ping pfsense IP 1.1, well not being able to ping something on say the 192.168.1.0/24 network but can ping pfsense 192.168.1.1 points to that device your trying to ping firewall or wrong gateway setup.

Sniff on the pfsense 1.1 interface, while you ping say 192.168.1.x from your 200 network, do you see pfsense send the pings on?

edit example... Here I know my work laptop security will not answer ping.. So pinging from my 192.168.9 network to its address 192.168.6.101, sniffing on pfsense 192.168.6 interface I can see pfsense send the pings, just no answers.

If your 200 vlan rules allow you to ping the pfsense 192.168.1.1 address, but you get no answer pinging something else on the 192.168.1.x network - this screams something on the device your pinging, be it firewall/security on it, wrong gateway, wrong mask.. But your mask looks right /24 255.255.255.0 if you had say a /16 on the switch, then yeah you would have problems talking to it from some other network that was anything 192.168

Ok this is interesting
All the switches are not visible in the scan. i can ping all ips here with no issues
[Ip scan form 200.xxx](Invalid file type. Allowed types are: .png, .jpg, .bmp, .txt, .gif, .xls, .gz, .zip, .pcap, .pcapng, .7z, .xml, .jpeg, .diff, .patch, .tgz, .tar, .0, .cap)

Well clearly sent it on.. so you not getting an answer is not pfsense.. I would validate in the arp table of pfsense that the mac address you show for 192.168.1.3 is valid for your 192.168.1.3 device.

But clearly pfsense sent on the traffic, it has no control if the device actually got it, or that it answers back to pfsense.

edit: how are you seeing mac address from device on another network.. Mac are only viable on the same L2 network.. There really should be no way to get a mac address for some device on another network.. the only mac you would send traffic to get off your network would be your gateways mac..

Brother I have no idea !!!

Oh and these are All Switches at Each Location 4 locations

[johnpoz]

@BigA so is that correct mac for 1.3?

As to your scan.. Showing that mac address for devices on another network points to lack of isolation between your networks..

Here so scanning from my pc with that same scanner - notice no mac addresses for anything on 192.168.2, but shows mac for everything on the same network 192.168.9

You got something else going on - pfsense clearly sent on the ping from your 200.x address to the mac it knows for 192.168.3 - if that device does not answer there is nothing pfsense can do about it.

@johnpoz
Looking at the Ip Scanner those MAC adresses are for HP printers tied to the network in other building.

I believe there must be some security feature in the switches that is stopping access.
