How to get 2 separate networks to talk to each other?

johnpoz · Feb 25, 2020, 2:16 PM

yes - exactly how your pinging from the lan interface.. Just pick the server interface... example

ilovechickennuggets · Feb 25, 2020, 2:18 PM

No, 100% packet loss

kiokoman · Feb 25, 2020, 2:40 PM

eh now i remember an old 3d where someone enabled static arp and was unable to ping
did you perhaps enabled static arp somewhere?

ilovechickennuggets · Feb 25, 2020, 2:47 PM

@kiokoman I have new information to present. I was doing my ping wrong using default as source. I was curious and tried again with LAN and also resulted in packet loss.

Static ARP is not enabled.

PING it from the SERVER IP of pfsense - change your source to server!!

Well sniff on pfsense server interface when you ping - looks like you have just plain connectivity problem..

kiokoman · Feb 25, 2020, 2:56 PM

the nas is out of the dhcp range, it must have a static entry, please check if you inadvertently enabled

ARP Table Static Entry Create an ARP Table Static Entry for this MAC & IP Address pair.

if so disable / untick it

or if you have set a wrong gateway (should be empty)

look in pfsense arp table - what does it show for this 70.2 IP

ilovechickennuggets · Feb 29, 2020, 6:47 PM

@johnpoz

@kiokoman
I did make a static entry under DHCP static mapping for SERVER interface as 192.168.70.2.

johnpoz · Feb 25, 2020, 3:05 PM

And your sure that is correct? there for your 70.2 address.

Sniff when your pinging from pfsense server interface... Do you see the traffic go out to the correct mac, if so if no answer its on the client or the connection to the client..

If pfsense can not talk to it from its own interface in the network, then its never going to work from a different network.

ilovechickennuggets · Feb 25, 2020, 3:08 PM

@johnpoz
Yup, I just checked the MAC address, it matches.
How do I sniff while pinging? Where do I find this in pfsense?

johnpoz · Feb 25, 2020, 3:20 PM

diag menu, packet capture...

kiokoman · Feb 25, 2020, 3:30 PM

@ilovechickennuggets
but you did not answer my question, put a screenshot of that static entry pls

I just want to let you you I appreciate and thank you for your patience. I am not too good with this area stuff. Here's what I got from the packet capture, hopefully with the right settings.

johnpoz · Feb 25, 2020, 3:38 PM

Well there are no pings in there..

So up the level of output so you can see the mac.. I think your mac is wrong to be honest. Since you set a static.

And when you did the sniff you did it at the same time as you were pinging?

Not seeing any response for dns in there either..

These are the current static mapping settings of the entry. The first shows pfsense. The second shows the MAC of the nas. So to make sure I was getting the right IP and MAC, I restarted my NAS. Somehow it gave me a new IP from dhcp. I did something wrong.

P.S. kiokoman, thank you for your help too!

johnpoz · Feb 25, 2020, 4:04 PM

And can you ping this IP?

ilovechickennuggets · Feb 25, 2020, 4:04 PM

@johnpoz
Yes the sniff happened at the same time as the ping.

After I restarted my NAS just now, it gave me new IP of 192.168.70.10 - which is the start of my DHCP range.

johnpoz · Feb 25, 2020, 4:05 PM

and can you ping that?

Can your nas ping pfsense 70.1 address?
