Intermittent Connection On One Machine
-
I have one PC that has intermittent connection issues with my TrueNAS machine, both web UI and SMB share. It mostly doesn't connect, but has once or twice. I have pfSense and TrueNAS both running on their own hardware. TrueNAS was virtualized on a Proxmox machine and running fine for years. I finally got TrueNAS moved to a Poweredge r510, and this has been going on since. Nothing changed in pfSense, and the TrueNAS config was copied to the new machine. I immediately thought it was a hardware issue. I tried different ports on my switch, different cables, and putting the PC in question on the wi-fi instead of plugging in. I have attempted to look through the pfSense logs, but I don't really know what I'm looking at. There seems to be so many that I don't even know where to start. I should mention I am also running AdGuard for a DNS server. Everything is up to date.
pfSense 2.8.1 - Mostly default. I have only changed the DNS settings and added some static IPs
I don't think this is a TrueNAS issue since it works everywhere else. Any help is appreciated. If nothing else I could use some guidance on which logs I should be checking.

Well I just tried to connect my Proxmox machine to my NAS and that won't connect either. That did remind me that I had trouble getting two of the VMs connected at first as well. They seemingly started working for no reason. They have not had a problem since. They can still connect the the SMB share, but the Proxmox host can not. My new Proxmox machine can connect to the SMB share, byt can not connect the repositories to download templates. That one seems like a DNS issue. I'm honestly beyond lost at this point. Everything I set out to do this weekend has ground to a halt until I get this sorted out.

Hello jay_k,
It sounds like a duplicate IP address issue on your local network or a problem with DNS.
Are you trying to reach your NAS by name or by IP?
I think you should proceed step by step. Try starting the troubleshooting from the beginning.
-
From your PC, ping the IP address of your TrueNAS. Is that okay?
-
From your NAS, can you ping the LAN address of your pfsense, can you ping some Internet address (google dns or any other) ?
-
From pfsense, go to
Diagnostics > ARP Table. See if you can find the IP address of your NAS.

@martinez Thank you for the reply. I've been stuck on this for a while. So my windows PC can ping everything fine even though it still can not access TrueNAS. TrueNAS however, can ping the pfSense machine, but I can not ping the machines that can't access it. So it can ping my plex container, which can access TureNAS, but it can not ping my old proxmox machine, which can not access TrueNAS. It also will not ping 1.1.1.1 or 8.8.8.8. The ARP table shows the TrueNAS IP and MAC address. All are correct and match the static IP assigned in pfSense and the output of ifconfig -a on the TrueNAS machine, and I don't see any duplicates in the table.
I did reset pfSense to factory default only readding my static IP addresses, and I have Adguard shut down for now. No change at all.
There's definitly no firewall rules set after the factory reset, so I can't imagen what is blocking that maching. Also TrueNAS is a fresh install. All I did was import my pool.
I'm sure there some log that I need to check next, but I don't know what it is. Thanks again.

I think I got it. I checked the DHCP box in the TrueNAS setting for the network adapter. That allowed me to ping outside my network, and brought up all the connections except my old Proxmox machine. The Proxmox machine had an old virtual network bridge that I hadn't used in a few years. Nothing was plugged into the port it was configured to, but guess what the IP was set to. The same as TrueNAS. So I just deleted all unused bridges and that fixed that one.
I knew this was going to be something simple, and probably self inflicted. lol
Thanks again for the help with this. -
indeed :) , glad you were able to resolve your problem
