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

Ok I did a complete shut down and reboot. The NAS is now getting the correct static IP. In Pfsense, under Status/ DHCP Leases -showing as online

I installed ARPing and ran it with following settings

As for SSH and tcpdump, I am going to need to educate myself on this because I'm treading onto something completely new to me. I'll be back try your advice after I go through some documentations and tutorials. I don't have SSH set up and it looks like I need to generate a key.

so arping works, but normal ping does not?

That just SCREAMS, SCREAMS!!! firewall on that box!!!

Correct, this is the newest try at pinging.

johnpoz · Feb 25, 2020, 10:24 PM

Well your clearly arping for the IP.. Which comes back with mac correct, and you got your dhcpd address you reserved. So you seem to not being answering..

The odd thing is you didn't show any pings going out even when you tried to ping.. Which makes no sense - unless you didn't do the sniff right..

Again can the server ping pfsense IP? Sniff when your doing that test..

@johnpoz
Sorry! Ran the sniff and ping from NAS server to 192.168.70.1 resulted in 100% packet loss.

Ok so your seeing traffic to pfsense interface on 192.168.70.1 - but no answers!

That points to firewall on pfsense, but that shouldn't stop you from pinging from pfsense unless you have an outbound rule on your lan.. Do you have anything in floating?

example

Well what interfaces do you have all those rules on? Its quite possible your blocking something in all those rules...

Disable them all for "testing"

Your lan and server rules mean nothing for pinging from pfsense - the only thing that could cause what seeing would be a outbound rule on your server interface blocking pfsense from sending the ping even..

What are you rules on your server interface?

ilovechickennuggets · Feb 29, 2020, 6:48 PM

@johnpoz
So counting from top to bottom, the first 11 rules (pfB_Top_v4 to pfb_TOR_v4) - all 11 have the same setting with block to WAN interface only (only WAN is highlighted in interface box).

Ok well your server interface rules would not allow ping.. So that explains why pfsense would not answer ping.

Set a rule to allow ping to pfsense server address.
And possible dns is not listening on on 70.1

Set your ping rule, and try to ping from server again to 70.1

ilovechickennuggets · Feb 25, 2020, 11:07 PM

@johnpoz
Is this the correct way to set up this rule?

No!

On your server interface allow ping to the server address.

You want to allow your server to ping pfsense server IP 70.1 - lets get that working atleast!

OH my GAWD!! dude... how is the dest 70.2 that is not pfsense IP address!!

Please set a rule on your server interface to allow PING to pfsense address server address.. And ping from your server..

ilovechickennuggets · Feb 25, 2020, 11:29 PM

@johnpoz
Sorry! Dumb mistake! Fixed it. I pinged from the NAS and resulted in packet loss

Well there is something major wrong... You sure pfsense IP is actually 192.168.70.1?

Can you use a different interface? You don't have any vlans setup or anything like that?

Why was there no answer to the dhcp you show there on port 67? You can arp, but not doing any sort of traffic... Makes no sense at all..

ilovechickennuggets · Feb 25, 2020, 11:45 PM

@johnpoz
The vlans are all on the LAN side (192.168.69.1) with switch.
The SERVER side has nothing, just a straight direct connection to NAS.

johnpoz · Feb 25, 2020, 11:47 PM

Well makes no sense at all... Do you have another interface you can use? Another cable.. Post a ifconfig output on pfsense. If it was a bad cable - you would think you wouldn't see the traffic too pfense, and you would see traffic out even if didn't get to the client when you sniff when you pinged.

ilovechickennuggets · Feb 29, 2020, 6:49 PM

@johnpoz
ifconfig

I do have one more open interface and 1 extra cable. Let's call it a day for now and maybe try some other time and set up the rules and etc for new interface.

Thank you both for your time today! @kiokoman

johnpoz · Feb 26, 2020, 12:47 AM

dude... How do you have 192.168.70.1 on igb2, and you also have it on igb1.70??

Pfsense shouldn't even let you do that - because the interfaces overlap!!

Yeah that is not going to work ;)
